✦ Synopsis

After the electromagnetic fields in a line are discussed, conformal mapping and the singular integral-equation technique are used to deri¨e the expression for the characteristic impedance of a rectangular ( ) coaxial cone transmission line with an offset inner conductor RCCTLO . Simple and ¨ery accurate formulas, based on only the spherical TEM mode propagating, for the capacitance and characteristic impedance are found in terms of complete elliptic integrals. The method enables the characteristic impedance of a GTEM cell to be e¨aluated accurately and easily.
