Abstract :
Periodic structures have a long history of being utilized to control electromagnetic scattering and radiation for various engineering applications. A new exciting class of periodic structures is the left-handed materials for which both the effective permittivity and permeability are negative. This article presents a new promising method for analyzing these types of structures. The method is capable of a fully 3D electromagnetic analysis over a broad frequency range in a single execution. It is based on the finite-element method in the time domain (FEM-TD) over a unit cell of an infinite periodic structure.
