Microwave Set

Equipment set for conducting wave optics experiments involving wavelengths in the cm range.

The Microwave Set includes a control unit, transmitter and receiver with antennae, to allow the user to explore a number of experiment topics. These include straight-line propagation of microwaves and reflection, absorption and transmission.

How Does the Microwave Set Work?

A transmitter with a horn antenna radiates a narrow beam of linearly polarised electromagnetic waves, with a wavelength of about 3cm. The direction of polarisation can be altered by rotating the antenna around the axis of propagation.

To detect the waves, a horn antenna receiver and a microwave sensor are provided. A control unit converts the intensity of the signal received into a proportionally large output voltage, which can be measured using a voltmeter.

It is also possible to switch on an acoustic signal with a volume that is proportional to the intensity of the signal.
