AB The subject of the paper is estimation of the accuracy and applicability of the numerical algorithms based on the methods of the geometrical and physical optics (GO/PO), and the finite difference in time domain (FDTD) method for analyzing the electromagnetic properties of two-dimensional reduced-size hemielliptical lenses that are the key elements of the dielectric lens antennas in the mm and submm wave range applications. The reference solution has been derived by the Muller boundary integral equations (IE) that provide the controllable accuracy of the numerical solution to the problem of the electromagnetic wave diffraction by a dielectric cylinder of an arbitrary cross-section. The numerical results concern the field characteristics in the near- and far-field hemielliptical lenses made of rexolite, quartz and silicon, considering both E- and H-polarizations. A special attention has been paid to analyzing the resonance inside the lens.
