Use of the finite difference time method to simulate an EM wave traveling in vacuum. It is
restricted to movement in one dimension and confined between two perfect conductive walls (a
perfect reflection of the wave is expected when incident to the walls).
Fly-through a 3D visualization of a typical propagation environment. The field strength intensity
radiating from a transmitter antenna is color coded from yellow (high) to green (low).
How a microwave oven heats food. He describes how the microwave vacuum tube, called a
magnetron, generates radio frequencies that cause the water in food to rotate back and forth.
