This chapter analysis an experimental of time reversal (TR) as a means to mitigate radiation effects for wired signal transmission. It also focuses on high-frequency (HF) broadband (BB) power line communication (PLC) signals but could be extended to narrow band (NB) PLC and other wired transmission systems, such as digital subscriber line (DSL) access. The chapter focuses on one of the main limitations related to the PLC technology, namely, the generation of unintentional radiated signal. This phenomenon is mainly due to the unbalanced nature of the electrical network. The TR technique, also known as phase conjugation in the frequency domain, was first used in the fields of acoustics. This concept has been successfully extended to electromagnetic waves, where the rich multipath channel provides excellent conditions for its application. In order to experimentally assess the use of TR as a method to mitigate electromagnetic interference (EMI) for wired communication, the experimental setup was used.
