How do I distinguish HE and EH type modes in exact analysis of multilayer circular waveguides?

When we study the exact mode analysis of circular waveguides (Ref. Light Transmission Optics by D. Marcuse and Fundamentals of optical waveguides by Okamoto), we get an eigen value equation. If we...

Why are TM waves needed to excite surface plasmon (SP) modes on a metal dielectric interface?

TE waves can not excite SP modes because TE waves doesn't satisfy the boundary conditions. Mathematically it is understandable. But is it possible to understand it on physical ground.

What is the difference between localized surface plasmons and surface plasmon polaritons on the basis of propagation constant?

We normally define a mode by its effective index or propagation constant. For a mode to be excited its refractive index should be greater than the cladding ref. index (in case of fiber,...
