Electromagnetic and Optical Pulse Propagation presents a detailed, systematic treatment of the time-domain electromagnetics with application to the propagation of transient electromagnetic fields (including ultrawideband signals and ultrashort pulses) in homogeneous, isotropic media which exhibit both temporal frequency dispersion and attenuation. The development is mathematically rigorous with strict adherence to the fundamental physical principle of causality. Approximation methods are based upon mathematically well-defined asymptotic techniques that are based upon the saddle point method. A detailed description is given of the asymptotic expansions used. Meaningful exercises are given throughout the text to help the reader's understanding of the material, making the book a useful graduate level text in electromagnetic wave theory for both physics, electrical engineering and materials science programs. Both students and researchers alike will obtain a better understanding of time domain electromagnetics as it applies to electromagnetic radiation and wave propagation theory with applications to ground and foliage penetrating radar, medical imaging, communications, and the health and safety issues associated with ultrawideband pulsed fields.

This volume presents a rigorous mathematical development of the fundamental Maxwell-Lorentz theory of microscopic electromagnetics and its relationship to macroscopic electromagnetics in complex media with particular emphasis given to temporally dispersive materials. The relationship between both the mathematical development and the physical interpretation of the classical electromagnetic field theory with the special theory of relativity is emphasized throughout the volume.

Rigorous development of the classical microscopic Maxwell-Lorentz theory Detailed development of the dipole radiation field from the Liénard-Wiechert potentials Correlation of the microscopic and macroscopic electromagnetic fields in linear media Detailed description of causal, physical models describing material dispersion Angular spectrum representation of pulsed radiation fields in linear, temporally dispersive media Includes supplementary material: sn.pub/extras

Klappentext

Electromagnetic & Optical Pulse Propagation presents a systematic treatment of the radiation and propagation of transient electromagnetic and optical wave fields (such as those used in ultrawideband radar and communications sysyems as well as in ultrashort pulsed optics) through causal, locally linear media which exhibit both temporal dispersion and absorption. Volume I presents a detailed, rigorous development of the fundamental theory of both time and frequency-domain electromagnetics, beginning with the classical Maxwell-Lorentz theory of microscopic electromagnetic fields and ist invariance in the special theory of relativity, the correlation of the microscopic and macroscopic fields, and the angular spectrum representation of pulsed radiation fields in causally dispersive media. The theory provides a rigorous framework for applied research treating temporally pulsed wave fields in dielectric, conducting and semiconducting materials. Volume II presents the asymptotic description of specific pulsed wave fields in both Debye and Lorentz model dielectrics, Drude model conductors and composite model semiconductors.
