| Abstract: | A new method of calculating the distributing capacitances for the striplineswith multi-parallel circular rods is introduced with the use of an equivalent polygon rodto simulate the inner circular conductor and with the help of conformal mapping technol-ogy.The method employing the limit theorem of variational principle is fast incalculating speed and accurate and it is used to develop CAD of supper-miniaturewaveguide cavity fiIters. |
