Dual resonant polarization-independent and wide angle metamaterial absorber in x-band frequency

This paper presents the analysis of dual-resonant polarization-independent metamaterial absorber with wide operating angle in X-band frequency. Two circular rings with different radius are used as resonating elements. The resonating elements which are made by copper are printed on two surfaces (top...
