Introduction
For maximum effectiveness and reliability, it is absolutely essential that all weapon systems function perfectly at any time, any place and any electromagnetic environment. Should the performance of any systems become degraded by electromagnetic interference (EMI) – by external or internal sources, such an occurrence can result in a disaster. To prevent degradation at any elec

the rack openings =0.10417/0.3=0.3472m2=0.35m2
Clear width of the opening at the rack = 0.35/1.2 = 0.3m
Total number of bars =(0.3×〖10〗^3)/25-1 = 11개
Provide bars with 10mm width
