Well known microwave cavity measurements for determining the plasma density n and the collision frequency v of electrons was improved to be applicable in a simple way to decaying plasmas. Previously, two different microwave frequencies have been required to determine both of the plasma prameters. In the present study we analyzed the general properties of a cavity, and propose an improved method to measure, simultaneously, n and v in a decaying plasma by using only one frequency. The principle is that both parameters are determined by detecting the phase in addition to the absolute value of the transmission coefficient through the cavity. Moreover, we derive various formulas that are useful for measuring both parameters under various assumptions. Various experimental demonstrations for our methods are carried out.
