Claim Text:
1. A blast frequency control panel consisting essentially of two abutting layers comprising: (a.) a corrugated structural armor plate layer having a generally planar orientation and a face surface: and (b.) a strike surface layer comprising the ballistic fabric comprising a continuous ballistic fabric abutting and covering the face surface of the corrugated structural armor plate layer, the continuous ballistic fabric having physical properties including: (c.) the blast frequency control panel having a total projectile blockage perpendicular to the generally planar orientation, the total projectile blockage defined by the number 1.00 minus the sine of a half angle of the included intersection angle multiplied by a quotient of total traversing port lateral area divided by face surface area plus total traversing port lateral area.
