ABSTRACT:
A solid state shutter for blocking EMP is disclosed. The shutter includes thin films of amorphous semiconductor material fro the Group V or VI elements deposited on a silicon dioxide substrate. An antenna senses incident EMP causing a trigger circuit to apply a voltage across the thin films. The thin films switch from a state of high resistance to a state of low resistance for blocking passage of the EMP.
