Diseño de filtros en guía rectangular usando estructuras PBG's

Abstract

A new application of dielectric periodic structures (also known as PBG) to build and design waveguide filters is presented. The periodic structures have some stop frequency bands, band gaps, defined by the geometry, within any mode can propagate through the structure. One could use this particular feature of the periodic structures to implement waveguide filters, or any other device with some frequency dependence [1,2]. In particular, we will focus in the description through an example of all the different effects produced by this kind of structures within a rectangular waveguide.
