| Popis: | Excitation of a horn radiator by the coaxial line connected to the radiator is considered. A finite electromagnetic pulse with the TEM structure propagates in the line. It is shown that cancellation of the symmetry of rotation about the Z axis of the shape of the horn head results in the appearance at the Z axis of the flow of the efficient electromagnetic radiation directed along this axis, which is caused by the conversion of the TEM mode into the modes with linear (near the Z axis) polarization inside the horn. The possibility of control of the calculation accuracy and support of a high accuracy of calculation (which, for the considered examples, is about 0.1% in terms of the energy norm) is demonstrated. |
