The rigorous solution of the problem about eigen resonant frequencies of H/sub ps0/ modes of the ferrite resonator in the waveguide is found. The dependencies of eigen resonant frequencies on material parameters of the ferrite resonator are analyzed. Some simple formulas in the analytic form for engineering computations of frequencies with a high degree of accuracy are received.
The excitation equations for the irregular helical waveguide are obtained on the basis of conversion of coordinates and using Galerkin's projection technique.
The frequency band properties of two closely positioned longitudinal slots in the broad wall of a rectangular waveguide (one being positioned in the middle of the wall) are studied. It is shown that this radiator is very efficient and narrow-band, especially, when the slots are filled with dielectric. The system of two double-slots is considered as well.
Given in this paper is the notion of a numerical experiment, its prospects and possibilities as a powerful tool in studies of physics and microwave technology. The requirements for mathematical models and calculation procedures are stated. The author proposes an effective technique of digitization for numerical calculation of differential equations. Propagation of an H/sub 10/ wave in a non-regular...
The procedures of the electrodynamical analysis of the axisymmetric devices based on quasi static definition and combination of the LC-circuits for 12 TEM waveguide, crossing the elementary grid volume, with borders in cylindrical coordinate system are described. For the axisymmetric devices the three-dimensional (3D) LC-grid transforms into the 2D LC-grid in radial cross section of devices with the...
