Mininec: A mini-numerical electromagnetics code

Abstract : An investigation of the merits of techniques that may result in a reduced version of an antenna modeling code applicable to small problems and small computer resources. The result is the identification of one promising numerical approach suggested by Dr DR Wilton of the University of Mississippi. The approach has been coded in BASIC and implemented on a microcomputer. The computer code has been dubbed MININEC (Mini-Numerical Electromagnetics Code). MININEC solves an integral equation relating the electric field and the vector and scalar potentials. The solution involves a modified Galerkin procedure. This formulation results in a compact code suitable for use on a microcomputer. MININEC solves for the impedance and currents on arbitrarily oriented wires including configurations with multiple junctions. Options include lumped impedance loading and far field patterns. MININEC has been written in the BASIC language compatiable with many popular microcomputers. MININEC has been implemented on the NOSC Univac 1100/82, the NOSC VAX, a CDI microcomputer, and an Apple microcomputer.
