Abstract

In this work, we present a statistical model for characterizing minimum values of the field or power inside a multi-path electromagnetic environment. It is found that, for both overmoded and undermoded regimes, generalized extreme value distribution leads to the reverse Fr\'echet and Weibull types for the Cartesian and total complex-valued field and the total energy (intensity). These stable dfs are allowed by convergent behaviour of a lower tail for parent Cartesian field df, namely a x2.
On the other hand, the received power exhibits a Pareto-type distribution, because of the unbounded left tail of the Rayleigh parent distribution.
