fDesc[0] = "BMTL can handle transmission lines with up to nine conductors and several transmission lines can be connected to each other. Excitation can be done by either voltage sources connected at the ends of the lines or incident fields. Lines are terminated in resistors. Computed quantities are voltages and currents along the lines which can be shown on the screen so that e.g. pulses travelling back and forth the lines can be seen. Also end responses, both currents and voltages, can be saved in files and be transformed to the frequency domain through an internal FFT routine. Properties of the transmission lines are described for the program by entering the inductance and capacitance matrices. These matrices can be read from files generated by the LC-Calc program. The program does not have a help file but the use of the program and the theory are described in the PDF-document.";
