Two-dimensional waveguide power transmission (2DWPT) can potentially provide a safe and wireless means of electricity transfer. Our goal is to develop a 2DWPT system in which the power is transferred only to special receiver devices and not to other objects. For this purpose a new high-quality-factor (high-Q) receiver coupler is designed while the Q factors of other general objects are reduced by a thick insulator layer on the sheet. This Q's contrast enables selective power transmission to the receiver coupler. In this paper we report on the experiment result of simultaneous power transmission to multiple receivers. In the case where eight 50-Ω loaded couplers operate on a 90 cm × 60 cm large waveguide sheet simultaneously, the overall microwave transmission efficiency achieved 87.7% at a maximum.
