Measure RF Isolation

Review on Measurement of RF Isolation for Small Enclosures:

In this paper, measurement method for 300 MHz – 6 GHz in chambers with dimension greater than 2.0 m is investigated. Also, methods for SE measurement in small chambers are introduced.

Shielding Effectiveness: magnitude ratio of signal received from transmitter antenna without shielding enclosure to the signal received within enclosure.

Shielding Enclosure: It is a structure that prevents any electromagnetic (EM) field  penetrate to its interior, and it also prevents environments from the effect of internal EM fields. In general, a shielded enclosure is constructed from metals with a continuous electrical connection in between metallic parts.
