What is atlc?
• Answer: atlc is a set of around 10 computer programmes designed for finding the properties (characteristic impedance, inductance per m, capacitance per metre, velocity factor, electric field distribution) of any transmission line with 2 or 3 conductors (i.e. a normal line or coupler). Some programs are used for design, other for analysis. The main program, which is called atlc itself, uses the finite difference method to determine these properties, so while slower than other methods, atlc can handle any cross section.
