Tunable Plasmonic Nanoparticles Based on Prolate Spheroids

Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...

Semi-Analytical Computation of Acoustic Scattering by Spheroids and Disks

Analytical solutions to acoustic scattering problems involving spheroids and disks have long been known and have many applications. However, these solutions require special functions that are not easily computable. Therefore, their asymptotic forms are typically used instead since they are more readily available. In this paper, these solutions are explored, and computational software is provide...

Numerical simulation of the whispering gallery modes in prolate spheroids

In this paper, we discuss the progress in the numerical simulation of the socalled ‘whispering gallery’ modes (WGMs) occurring inside a prolate spheroidal cavity. These modes are mainly concentrated in a narrow domain along the equatorial line of a spheroid and they are famous because of their extremely high quality factor. The scalar Helmholtz equation provides a sufficient accuracy for WGM si...
