Introduction
The experiments are designed to give a thorough introduction to wave theory using the Microwave Optics System. Basic prin-
ciples are only briefly discussed in each experiment because it is assumed that the students have the appropriate theoretical
background. These experiments range from quantitative investigation of reflection and refraction to microwave models of the
Michelson and Fabry-Perot interferometers. Experiments for investigating Bragg diffraction and Brewster’s angle are
included, but require the Microwave Accessory Package.
The experiments are written in a worksheet format. Fee free to copy the experiment write-ups for use in your lab.
Microwave Optics System Equipment
The Complete Microwave Optics System consists of the Microwave Optics System (WA-9314C) and the Microwave Acces-
sory Package (WA-9315). The Microwave Optics System comes with a 2.85 centimeter wavelength microwave transmitter
and a receiver with variable amplification from 1X to 30X. All the accessory equipment needed to investigate a variety of
wave phenomena is also included.

*The Cubic Lattice contains 100 metal spheres in a 5 by 5 by 4 array.
Assembling Equipment for Experiments
The arms of the Goniometer or the Fixed Arm Assembly slide
through the holes in the Component Holders as shown. Make
sure the magnetic strip on the bottom of the arm grips the base
of the carriage. To adjust the position of the holders, just slide
them along the arms. Attach the mounting stands of the micro-
wave Transmitter and Receiver to the arms of the Goniometer
or Fixed Arm Assembly in the same manner.
For most experiments it is advantageous to attach the Transmit-
ter to the long arm of the Goniometer and the Receiver to the
shorter, rotatable arm. This maintains a fixed relationship
between the microwave beam and components mounted on the
long arm (or on the degree plate) of the Goniometer. In turn the
Receiver moves easily to sample the output.
