Abstract

Water is a promising dielectric material for broadband absorption of great interest for microwave applications due to their dispersive characteristics and imaginary permittivity part. In this work, several broadband absorbers operating in the microwave between 5.0 Ghz to 30.0 Ghz will be analyzed. Higher absorption for TE and TM polarized electromagnetic waves with efficiency above 90% has been observed for microwave frequencies while optical transparence can occur simultaneously. The analyzed water-based metamaterial absorbers exhibit a wide-angle absorption. These kind of structures can be applied to stealth and electromagnetic compatibility technology.
