Deduction of formulas for electrical parameters of common vertexcoaxialcircularconeslike and disklike ideal transmission lines

The paper has derived the formulas from Ampere's Law and Gauss law, which are used to evaluate the electrical parameters of commonvertexcoaxialcircularconeslike and disklike ideal transmission lines, such as capacitance, inductance and impedance. However, some of these formulas are analytical expressions while the others are only some method to get numeric solution. The expressions or method has been validated by a practical example and sequentially used to evaluate a new design.
