To make a seawater antenna, the current probe (an electrical coil roughly the size and shape of a large doughnut) is attached to a radio’s antenna jack.
A large disc-shaped rectifying antenna attached to the fuselage harvested the microwave energy, turning it into direct current to power an electric motor attached to the plane's propeller.
机身上的圆盘形整流天线能接收地面传输的微波能，将其转化为直流电为飞机推进器上的电动机供能。

In such a device, the antenna would concentrate photons before the photovoltaic cell converts them to an electrical current.
