The current rapid and complex advancement applications of
electromagnetic (EM) and optical systems calls for a much needed
update on the computational methods currently in use. Completely
revised and reflecting ten years of develoments, this second
edition of the bestselling Computational Methods for
Electromagnetic and Optical Systems provides the update so
desperately needed in this field.
Offering a wealth of new material, this second edition begins
with scalar wave propagation and analysis techniques, chiral and
metamaterials, and photonic band gap structures. It examines
Pontying vector and stored energy, as well as energy, group, and
phase velocities; reviews k-space state variable formation with
applications to anistropic planar systems; and presents full-field
rigorous coupled wave analysis of planar diffraction gratings with
applications to H-mode, E-mode, crossed gratings, single and
multilayered diffraction grating analysis, and diffraction from
anistropic gratings.
Later chapters highlight spectral techniques and RCWA as applied
to the analysis of dynamic wave-mixing in PR materials with induced
transmission and reflection gratings and demonstrate the RCWA
algorithm to analyze cylindrical and spherical systems using
circular, bipolar cylindrical, and spherical coordinates. The book
concludes with several RCWA computational case studies involving
scattering from spatially inhomogeneous eccentric circular
cylinders, solved in bipolar coordinates. Many of these examples
apply the complex Poynting theorem or the forwardscattering
(optical) theorem to validate numerical solutions by verifying
power conservation.
Using common computational tools such as Fortran, MATLAB,
COMSOL, and RSOFT, the text offers numerous examples to illuminate
the material, many of which employ a full-field vector approach to
analyze and solve Maxwell 's equations in anisotropic media where a
standard wave equation approach is intractable. Designed to
introduce novel spectral computational techniques, the book
demonstrates the application of these methods to analyze a variety
of EM and optical systems.
