In this paper, the dispersion analysis is proposed for the characterization of natural modes of a metamaterial formed by pairs of metallic Jerusalem crosses separated by a thin dielectric layer. It is shown that the modal spectrum includes bound (proper real) and leaky (proper and improper complex) waves. An interesting observation is that at low frequencies a peculiar dominant TM improper leaky wave occurs, which is shown to be related to peaks of complete transmission.

Abstract
In this paper, the dispersion analysis is proposed for the characterization of natural modes of a metamaterial formed by pairs of metallic Jerusalem crosses separated by a thin dielectric layer. It is shown that the modal spectrum includes bound (proper real) and leaky (proper and improper complex) waves. An interesting observation is that at low frequencies a peculiar dominant TM improper leaky wave occurs, which is shown to be related to peaks of complete transmission.File in questo prodotto:
