Band-gaps electromagnéticos con celdas unidad de tres dieléctricos

Abstract

Electromagnetic band-gap structures (EBG) with Kronig-Penney morphology implemented inside rectangular waveguides are theoretically and experimentally examined using a unit cell with three dielectrics. Filtering properties of these structures are analysed, invoking the Floquet theorem for ideal structures (infinite in the propagation direction), and by means of the scattering matrix technique for real structures (i.e., of finite length). Measurements of the transmission coefficient for the fundamental mode in the Ku-band are presented.
