Polarisation of Microwaves Apparatus.
Description
The microwave transmitter is directed at a wire grid composed of parallel wires spaced approximately 1 centimetre apart. With the transmitter vertical,it is found that the signal received is a minimum when the wires are also vertical. No reduction in intensity when the wires are perpendicular to the transmitter.
