Shielding Effectiveness Calculator

A Clemson ECE693 Project by J. Curtiss Fox

Calculates the plane wave shielding effectiveness of various materials using the equation:
Shielding Effectiveness in dB equals reflection component plus absorption component
as described in the CVEL Shielding Theory Notes.
