I will design and simulate a microwave absorber in cst studio suite

This metamaterial absorber consists of a patterned metallic resonator (square and circular rings), a dielectric substrate, and a metallic ground plane. The resonator generates electric and magnetic resonances when illuminated by an electromagnetic wave. The ground plane suppresses transmission, while dielectric and conductor losses dissipate the trapped electromagnetic energy as heat. By achieving impedance matching with free space, reflection is minimized and near-unity absorption is obtained at the designed resonant frequency.
