Abstract
The present disclosure is directed to systems and methods for operating, designing, testing and verifying the performance of wireless communication devices. Specifically, the present systems and methods can passively attenuate unwanted electromagnetic interference (EMI) without degrading signal quality of predetermined frequency using a novel versatile module including a RF absorbing material in a composite medium surrounding the conducting signal lines. Utilizing varying permeability media, the present invention offer a robust platform to eliminate unwanted noise while maintaining a desirable control and power interfaces used for testing of wireless communication systems.
