Abstract :
A dual-band polarization insensitive absorber has been designed and studied in this work. Unlike previous dual band absorber composed of composite structures, only one square metal ring with a slit at the middle of each side has been designed to achieve dual-band absorption. The calculated results show two distinct absorption peaks of 0.96 at 10 GHz and 0.99 at 20 GHz. This dual-band absorber has many potential applications in scientific and technological areas because of its excellent absorption characteristics and concise structure.
