Abstract
In this reply, we clarify the assumptions under which the upper bound on the total active reflection coefficient (TARC) corresponds to the transducer efficiency figure. We point out that this equality is valid in certain cases only and is usually not represented in practice. The reasons for this statement are centered on the difference between available and input power, and the assumption of dealing with a lossless multiport antenna.
