摘要：

This paper presents a new concept of unidirectional scattering mitigation transmitarray (TA) using a single substrate frequency selective surface (FSS). This engineered electromagnetic surface formulates complementary fields for rendering obstacles to become electromagneticallytransparent without blockage modification. Spatial impedance distribution of the proposed TA is calculated by superposition and linearity. A double-layer FSS, which features wide tunable transmission phase shift range within 1-dB transmission loss, is implemented for proof-of-concept demonstration. The proposed cloaking technique is confirmed by full-wave simulations and measurements at 30.0 GHz.
