Abstract MTL (Multiconductor Transmission Line) inductance matrix is commonly computed through complex and tiresome indirect transform method, so a novel method to directly compute the MTL inductance matrix is proposed. Double filaments circuit is utilized to construct a matrix model, and then inductance matrix is directly solved from the model by the novel method, so the complexity of the analysis is greatly reduced. Additionally, matrix transformation is adopted; therefore, currents distribution can also be supplied when inductance matrix calculation is finished, which is impossible for classical indirect method. The novel method imports nonmagnetic quasi-static hypothesis and filaments division, then it can be applied to the transmission line structure with arbitrary shaped cross-section, and arbitrary separate distance in wide frequency band. Simulations show that this method has a good precision in currents distribution and inductance matrix calculation.
