A Novel Design of Metamaterial Absorber for Polarization Insensitive Incident Angle in the Execution of Dual-Band
Abstract
In this paper, We present a design and simulate of a dual-band and polarization insensitive for metamaterial (MTM) absorber in microwave frequency. The structure with thickness 0.05 mm comprises an outer Square ring, and Two split Circular rings incorporated with four square rings which will absorb to all incident electric and magnetic fields within a single copper sheet isolated by FR4 (4.4) substrates. The metamaterial absorber has been observing two absorption peak; one at 3.5GHz and 5.5GHz frequency mimicked with an absorbance of 99% respectively. WiMax is one of them that give high speed communication with full scope. Both frequencies work on Wi-Max application. The wide incident angle point starting range from 00 to 500 for both transverse electric (TE) wave and transverse magnetic (TM) wave. This MTM structure used for Wi-max application. After that, in this paper introduced its proposed design and simulation result that is executed in the CST Microwave studio software (frequency domain solver).
