Reflection loss in the case of plane waves impact on infinite absorbing slab

The paper deals with the theory and measurement technique concerning the electromagnetic radiation reflected by a conductive or semiconductive absorbing shield placed in the Fraunhofer region, in connection with the shielding effectiveness equations. It is shown that actual modeling of reflection loss is not correct and a solution is proposed. Together with the demonstration of the correct equation describing the reflected wave authors propose an error analysis and a measuring method as application in EMC.
