Abstract:

The goals of this project were to perform and publish mathematical research on wavelet signal processing, periodic composite dielectrics, and complete some work on the dispersion of water from a previous AFOSR grant. The wavelet studies were directed toward nondestructive evaluation using ultrasonic waves. The novel dielectrics were mainly the PBGS, photonic band structures-periodic arrays of a dielectric with permittivity ea embedded in a background dielectric with permittivity eb. Several types of disorder of these periodic objects were also studied.
