interference effects in scattering problems
An ultrasonic (real measurement) version of the JAVA scattering app
A "band gap" occurs when the transmission coefficient goes to near zero and the reflection coefficient goes to near 1. Here is an example of a measured photonic band gap in a layered medium (quartz and teflon) measured with millimeter electromagnetic waves in my lab.
