N2 - In Dynamic Wireless Power Transfer, the embedment of power transmission coils in the road surface is essential. Previous studies have reported that coil characteristics deteriorate during embedment in reinforced concrete pavement due to the effects of rebar and concrete. In this paper, precast reinforced concrete pavement slabs employing insulated steel bars were used to simulate the embedment of coils in the pavement, and the coil properties due to the embedment were measured. An embedment method using polyurea resin is proposed to reduce the effect of concrete on the coil properties. The results of the embedment simulation test showed that the use of polyurea resin successfully improved the Q-value of the coil by about 85 % compared to the case where concrete was used. Furthermore, the transmission characteristics were evaluated using a vector network analyzer (VNA), and a transmission efficiency of 95.8 % was obtained over a transmission distance of 170 mm.
