Abstract :
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 subsequent transition to a flat R-grid. The algorithm of the analysis of these grids is mastered in the professional program TAMIC-R-H, ensuring operation in time domain with grids having more than 10/sup 7/ elements.
