In an aircraft, to protect a PCB from external interference signals it is housed in an Aluminum(Al) Box (this is normally referred to as shielding). Conductivity of Al is 38.2 x 106 S/m & µr = 1. What shall be the minimum thickness of the Al sheet from which this box is made, if we have to block 1.6 MHz interference signal from passing through this sheet?
