Propagation properties of guided surface polaritons — a new class of electromagnetic waves

摘要

The propagation properties and field structures of a new class of electromagnetic surface excitations, the so-called guided surface polaritons, are investigated. These waves exhibit features of both film-guided modes and surface polaritons. The conditions of their existence dependent on the optical constants are discussed. The three-dimensional waveguide problem is treated by a rigorous mathematical formalism.
