Electromagnetismo con Aplicaciones: A Comprehensive PDF by Kraus

Electromagnetism is one of the fundamental forces of nature that governs the interaction between electrically charged particles. It is also the basis of many phenomena and applications in science, engineering, and everyday life, such as electricity, magnetism, light, radio waves, microwaves, lasers, and more.

However, learning electromagnetism can be challenging for students and professionals alike, as it involves complex mathematical concepts and equations. That is why a good textbook is essential for mastering this subject.

One of the best textbooks on electromagnetism is Electromagnetismo con Aplicaciones, written by John D. Kraus and Daniel A. Fleisch. This book is the Spanish edition of Electromagnetics with Applications, which is widely used and praised by instructors and students around the world.

In this book, Kraus and Fleisch do a superb job of blending Kraus's classic writing style with innovative organization. This text is designed so that the first five chapters contain the core content while the latter six provide supplementary material. This flexible organization makes it easy to teach and learn the material in a way that meets specific course needs.

The book covers all the topics of electromagnetism in a clear and concise manner, with numerous examples, problems, figures, and tables. It also includes practical applications of electromagnetism in wireless systems, bioelectromagnetics, electromagnetic effects in high-speed digital systems, and numerical methods.

The book is available in PDF format, which makes it convenient to access and read on any device. The PDF also contains computer programs, project equipment, answers to selected problems, and other useful resources.

Some of the topics that the book covers in detail are:

Electric and Magnetic Fields

This chapter introduces the basic concepts and laws of electric and magnetic fields, such as Coulomb's law, Gauss's law, Ampere's law, Faraday's law, Lorentz force, and Biot-Savart law. It also explains how to calculate the electric and magnetic fields due to different charge and current distributions, such as point charges, line charges, surface charges, volume charges, current loops, solenoids, and toroids.

Transmission Lines

This chapter covers the theory and applications of transmission lines, which are devices that carry electromagnetic waves from one point to another. It explains how to model transmission lines as lumped or distributed circuits, how to analyze their voltage and current waves, how to measure their characteristic impedance and reflection coefficient, and how to design matching networks and stubs. It also discusses the types and properties of different transmission lines, such as coaxial cables, microstrip lines, striplines, and waveguides.

Wave Propagation, Attenuation, Polarization, Reflection, Refraction, and Diffraction

This chapter deals with the propagation of electromagnetic waves in different media and environments. It describes how to derive and solve the wave equation for uniform plane waves in free space, lossy media, good conductors, and good dielectrics. It also explains how to characterize the polarization, attenuation, phase velocity, group velocity, wavelength, frequency, and power of electromagnetic waves. It further explores how electromagnetic waves interact with boundaries and obstacles, such as reflection, refraction, total internal reflection, Brewster's angle, Snell's law, Fresnel's equations, critical angle, evanescent waves, Huygens' principle, Fraunhofer diffraction, and Rayleigh scattering.

Antennas, Radiation, and Wireless Systems

This chapter introduces the principles and applications of antennas, which are devices that convert electromagnetic waves into electric currents and vice versa. It explains how to calculate the radiation pattern, directivity, gain, beamwidth, polarization, input impedance, and efficiency of different types of antennas, such as dipoles, loops, arrays, horns, reflectors, and microstrip patches. It also discusses the design and performance of wireless systems that use antennas for communication and radar purposes.

Electrodynamics

This chapter covers the advanced topics of electrodynamics, which is the study of electromagnetic fields in relation to the motion of charged particles. It derives and applies the Lorentz transformation, the relativistic form of Maxwell's equations, the conservation laws of charge and energy-momentum, and the Poynting vector. It also explores the concepts of electromagnetic potentials, gauge invariance, retarded fields, radiation reaction, Larmor's formula, and Liénard-Wiechert potentials.

Dielectric and Magnetic Materials

This chapter deals with the properties and effects of dielectric and magnetic materials in electromagnetic fields. It defines and measures the permittivity and permeability of materials, and how they affect the capacitance and inductance of circuits. It also explains how to model dielectric and magnetic materials as polarized media with bound charges and currents. It further describes the phenomena of polarization, magnetization, hysteresis, ferromagnetism, paramagnetism, diamagnetism, piezoelectricity, and pyroelectricity.

Waveguides, Resonators, and Fiber Optics

This chapter explains the theory and applications of waveguides, resonators, and fiber optics, which are devices that confine and guide electromagnetic waves along a certain path. It describes how to analyze the propagation modes, cutoff frequencies, dispersion relations, field patterns, power transmission, and losses of different types of waveguides, such as rectangular, circular, and dielectric waveguides. It also discusses the principles and design of resonant cavities and microwave filters, which are used to select or reject certain frequencies of electromagnetic waves. It further introduces the concepts and applications of fiber optics, which are thin strands of glass or plastic that transmit light signals over long distances.

Bioelectromagnetics

This chapter explores the interaction of electromagnetic fields with biological systems and tissues. It covers the topics of bioelectricity, biomagnetism, electric stimulation, electroporation, electrocardiography, electroencephalography, magnetocardiography, magnetoencephalography, magnetic resonance imaging, microwave diathermy, hyperthermia therapy, and electromagnetic compatibility. It also discusses the safety standards and guidelines for human exposure to electromagnetic fields.

Electromagnetic Effects in High-Speed Digital Systems

This chapter examines the electromagnetic effects that occur in high-speed digital systems, such as computers, communication devices, and integrated circuits. It explains how to model digital signals as voltage and current waves on transmission lines, how to measure and reduce the signal integrity problems of crosstalk, reflection, ringing, overshoot, undershoot, and ground bounce. It also describes how to design and test the electromagnetic compatibility of digital systems with respect to radiated and conducted emissions and immunity.

Numerical Methods

This chapter introduces the numerical methods that are used to solve electromagnetic problems that are too complex or irregular for analytical solutions. It explains the basic concepts and algorithms of finite difference, finite element, and boundary element methods, and how to apply them to solve electrostatic, magnetostatic, and time-dependent problems. It also discusses the advantages and disadvantages of each method, and the criteria for choosing the appropriate method for a given problem.
