Metematerial to real ground transition for HF surface wave radar

, 2014
For many years, researches on “over the horizon” radar are investigated, especially on the High Frequency Surface Wave Radar (HFSWR), which is dedicated to the maritime surveillance. In order to increase the efficiency of the HFSWR, we focus on the electromagnetic field radiated at low elevation angle.
