Modeling of Optical Nanoantennas.This book introduces several key techniques for such modeling, many of which are used in commercial design tools. The absorption, scattering, and extinction fields of a homogenous and coated spheroidal nanoparticles in a variety of surrounding medium due to an incident plane wave is studied. The applicability of the modified long wavelength approximation to ellipsoidal particleswith size less than 10% of the incident wavelength was discussed, and an analysis of its accuracy in comparison to Mie theory and measured experimental results was presented.The optical...
