The study introduces an approach in developing a virtual laboratory that can be used for classroom instruction as well as distance learning and is a good alternative to highly expensive microwave measurement equipment. The software package is written in C++. The testing results of applying a virtual laboratory for radiophysics measurements are considered.

the solution of the boundary problem of diffraction and excitation of system of carbon nanotubesvibrators is reduced to solving of the integral equation with a logarithmic kernel. After regularization, integral equations were solved by means of collocation method. The character of behavior of the current on the vibrator's ends was considered. The existence of resonances at the frequency range 0.1-1.0THz was shown.
