In this paper, we propose a practical study of the microwave characteristics filter based on metamaterials that is characterized by an index of negative refraction. We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lengths of electromagnetic metamaterials, in order to determine the effective refractive index from the effective permittivity...
This paper proposes patch antenna for X-band [8.2 GHz; 12.4 GHz] and military applications, enhanced by double negative metamaterial complementary (C-DNM) cells. Two different structures will be presented and discussed, which involve: (1) C-DNM with square patch antenna, and (2) C-DNM with circular patch antenna. The antenna was designed with resonance frequency around at 12 GHz. The metamaterial...
