Abstract

Shielding effectiveness measurements in an anechoic chamber are often too time consuming and expensive to be performed on most product enclosures. A method is proposed to estimate and improve the shielding effectiveness of a metal enclosure that contains no RF absorbing materials, in "real time," on a benchtop, using only a scalar network analyzer. This method uses the input power and the reflection coefficient of the source to estimate the transmission coefficient and the total radiated power
