Air-Ground Impedance Matching by Depositing Metasurfaces for Enhanced GPR Detection

Deeply buried inclusions such as pipes and cables cannot be detected when the air-ground interface suffers severe impedance mismatch, resulting in little electromagnetic (EM) signals penetrating the subsurface, even before the scattering and reflection from the buried inclusions occur. Therefore, increasing the penetration depth by effectively enhancing the EM transmission into the lossy subsurfac...
