Coherent Jamming with 1-Bit Time Modulated Digital Metasurfaces

A coherent jamming system to suppress the fundamental component with 1-bit time modulated digital metasurfaces has been proposed in this paper. With dynamically controlling the reflection phase coefficient of the elements, the energy of fundamental component of the jamming signals can be significantly suppressed, which can effectively reduce the exposure risk of the factual position and improve the jamming performance. The simulated result verified the effectiveness of the proposed method.
