The full-wave Maxwell simulations on electromagnetic wave propagation based on a finite difference time domain method are performed to study the shift in cutoff density due to relativistic electron mass modification. The simulations on one-dimensional ultrashort-pulse reflectometry are also performed and the density-profile reconstruction is shown to have an underestimated density profile by the relativistic effect, and an idea of electron temperature estimation by means of reflectometry is discussed. Its related technology such as metallic wire-made discrete waveguide and beam former is also briefly discussed.
