Abstract

In this letter, resonance properties of a miniaturized rectangular cavity resonator (MRCR) based on anisotropic metamaterials bilayer are investigated. The resonance equations for the electromagnetic wave in a rectangular cavity filled with anisotropic metamaterials bilayer are solved and analyzed first. It is shown that, different from the isotropic case and the one‐dimension (1D) resonator, the resonance properties of such a cavity are closely related to the dispersion relation of the anisotropic medium, which brings more design flexibility and tolerance for miniaturizing a conventional rectangular cavity resonator. As an example, a MRCR loaded only with negative permeability medium is designed and numerically simulated. It is shown that the resonant behavior is successfully observed, and the width and length of the MRCR are simultaneously shortened by 70%, compared with a conventional rectangular cavity resonator dimension. © 2008 Wiley Periodicals, Inc.

## Abstract A partially reflective metamaterial surface is designed to have in‐phase reflection property for the purpose of reducing the height of resonant cavity antennas. Since the reflection phase of the in‐phase is close to 0° at the operating band, the cavity height, that is, the distance betw
