Abstract :
Investigation of a wideband flexible microwave absorber with an inhomogeneous resistive sheet made of ink with graphene nanoplatelets is presented in this paper. The analysis is performed for an obliquely incident plane wave of both TE and TM polarizations. It is shown that the absorber´s angular performance can be improved applying a cellular spacer with resistive stripes printed on its vertical sides. The results of full wave electromagnetic simulations are presented and discussed.
