Abstract :
Effects of wetting on wireless power transmission by an open-ring resonator coupling (ECOR) were investigated. Using sheets of paper wetted with deionized, tap, and sea waters as intervening materials, s-parameters were measured between two open-ring resonators on separated printed boards designed for 2.45GHz power transmission. The peak s21 degraded and the bandwidth shrank as the number of wet paper sheets increased. The results are compared with electromagnetic simulation using the complex dielectric constants and the conductivity of the waters.
