title = "Design of Absorber for Special Angle Oblique Incidence in Dual Modes",
abstract = "A novel absorber for special large angle of oblique incidence in dual modes is proposed in this paper. The proposed structure consists of an outer metal ring loaded with resistances, and a metal square slot in the middle. As it is known that in different modes, the wave impedance of free space has the opposite trend with the increasing of oblique incident angle. It is difficult to match the impedance of free space with two modes. Therefore, we propose an asymmetric absorber structure which can match the free space impedance of TE-and TM-modes in horizontal and vertical directions, respectively. The simulation results show that when the oblique incident angle is in the range of 60 to 70 degrees, the bandwidth is 5GHz (from 4.93GHz to 10.06GHz) with a low reflection response (\textbackslash{}vert\textbackslash{} \textbackslash{}mathrm\{S\} \{11\}\textbackslash{} \textbackslash{}vert <-10\textbackslash{}text\{dB\}) for both TE-and TM-mode.",
