Exact mutual impedance between sinusoidal electric and magnetic dipoles

Analytic expressions are presented for the exact mutual impedance of sinusoidal electric and magnetic monopoles in a homogeneous medium. Numerical computations are carried out and presented. It is shown that computed values of mutual impedances for both linear monopoles and surface-patch monopoles in the near-overlapping case exhibit an excellent convergence to the theoretical values when monopoles are physically overlapped. This demonstrates the robust accuracy of the presented expressions in the near-singular integration kernel for the mutual impedance computation. The expressions are also compatible with existing techniques. Minor modifications are needed to enable existing programs to compute such mutual impedances
