An ultra thin metamaterial absorber using electric field driven LC resonator with meander lines

This paper describes the electric field driven LC (ELC) resonator structure using Meander lines in C-band. The proposed ELC driven metamaterial structure is simulated using Ansoft HFSS which shows an absorption peak at 6.26 GHz with absorbance of 99.1% and S11 of -20.55 dB. The reduction of frequency at which absorption occurs can be explained from the equivalent LC circuit combination of the proposed structure. The incorporation of Meander lines enhances the net inductance, and thus frequency is reduced. The absorbance is supported by the real and imaginary parts of the impedance value extracted from S-parameters. The absorption frequencies can be shifted by varying the gap as well as length-segment of the Meander Line structure.
