Design of metamaterial

Abstract

Meta materials are artificially designed materials that exhibit very high transmission values within a frequency range. Double Negative (DNG) Meta material shows both negative permittivity and negative permeability within a certain frequency range. It is composed by an array of Split Ring Resonators (SRRs) and an array of Capacitive Loaded Strips (CLSs). This paper presents the design of a new meta material structure. As compared to conventional Double Negative Metamaterial in Reference[3], the size of the new structure is 70% reduced and hence this leads to a size miniaturization in various meta material applications specially in antenna application. It can also be used in very high frequency applications, as its operating frequency is considerably high (30-40 GHz). Both the conventional and new metamaterial structure is simulated by CST Microwave Studio. In the metamaterial structure, dimensions has been varied many times and simulated in CST to observe the behavior of meta material and also theoretical explanations have been given for the observed shift in resonance frequency.
