In the case of an MGTL longitudinal currents are absent; the interpretation for the pul transverse inductance matrix [L.sub.T] can be found in terms of magnetic energy storage in the volume of the dielectric medium--due to the presence of stray magnetic field lines between magnetic wires, which give rise to magnetic voltages.
In the case of an MGTL electric charges are absent; the interpretation for the pul longitudinal capacitance matrix [C.sub.L] can be found in terms of electric energy storage in the volume of the dielectric medium--due to the presence of electric induction field lines encircling the magnetic wires, created by time-varying magnetic fluxes flowing longitudinally along the wires.
In (20), [[bar.Z].sub.T] is the pul transverse impedance matrix of the MGTL (units: [ohm]/m), and [[bar.Y].sub.L] is the pul longitudinal admittance matrix of the MGTL (units: S/m).
A simple MGTL configuration consisting of three equidistant circular cylindrical magnetic wires (Figure 5) is used to illustrate the application of the theory developed in the preceding sections.
Results showed that the MGTL has a superluminal phase velocity and zero, or almost zero, attenuation dispersion in a wide frequency band.
For ideal MGTLs ([[mu].sub.m] = [infinity]), [R.sub.m] = 0 is obtained.
This result suggests that MGTLs are expected to perform better at high frequencies than at low frequencies.
The discussion of the advantages or disadvantages of MGTLs versus electric transmission lines makes little sense unless concrete design goals are set.
A novel theoretical development on magnetic transmission line analysis aimed at the generalization of former research work on two-wire homogeneous MGTLs to multiwire inhomogeneous systems was presented.
