With the continuous arrival of diverse applications of the wireless technologies a smart manage of signals have demanded to improve software and hardware interfaces that enables us to apply well known among advanced technologies the so-called in-band-full-duplex (IBFD) by which one expects to improve multi tasks processes that a modern network requires to. In this paper we focus in the problem of self-interference cancellation IBFD processes through electrodynamics-based wave solutions. We used well-known solutions by which we can manage the interference through the tunable character of hardware schemes that to some extent allows us to reject noise without to compromise the signal.
