Convenient formulas are deduced, which relate electron densities and collision frequencies of uniform dense plasmas to two standing wave signals of a probing microwave reflected at a plane boundary of the plasma. In an experiment with a uniform afterglow plasma produced in a waveguide, the electron density from 2 x 10/sup 13/ cm/sup -3/ to 3 x 10/sup 11/ cm/sup -3/ is measured with reasonable value of the collision frequency by using a X-band microwave. The technique provides a mean for detecting an electron density as high as 1 x 10/sup 16/ cm/sup -3/ with the X-band microwave. (auth)
