In this paper we apply novel Spectral Ray Tracing (SRT) technique to analyze scattered field of a Gaussian beam hitting a cylindrical object. The simulated scattered field results using SRT is compared to FEKO simulation results using Method of Moment for verification. The frequency of Gaussian beam source is 500 GHz and the size of the cylinder compared to the wavelength is in the order of several wavelengths. Increasing the size of cylinder causes the shortage of computing resources for memory and processor time using commercial software, however, SRT can still handle electrically big scattering problems without encountering limitation in computing resources.
