摘要

Some filters for rectangular monomode waveguides are researched. They are based on metasurfaces composed of resonant subwavelength slots. It has been possible to verify, by means of numerical simulations, a significant improvement of their performance by just introducing several resonators in the cross section and certain mirror symmetry which avoid the splitting of the resonance frequency when elements are vertically stacked.
