The antennas-scatterers Analysis Program (ASAP) for thin wire structures in a homogeneous conducting medium performs a frequency domain analysis of antennas and scatterers, The program is applicable in the presence of a ground {that has} either perfect or finite conductivity. This appendix will describe the computer program which accomplishes this. Although the program was written for the IBM 360 computer system it can be executed on another system with minor modifications.
A piecewise-sinusoidal expansion is used for the current distribution, The matrix equation ZI = V is generated by enforcing reaction tests with a set of sinusoidal dipoles located in the interior region of the wire. Since the test dipoles have the same current distribution as the expansion codes, this may be regarded as an application of Galerkin's method. Rumsey's reaction concept was most helpful in this development, and therefore the formulation is known as the "sinusoidal reaction technique".
The main routine and each subroutine is discussed separately in this appendix, The writeups for the subroutines are arranged alphabetically by subroutine name after the main program, Each of the discussions includes the purpose of the subroutine, brief description, and a listing. {The listing is not included here as the source code is available and can be viewed with an editor} After the subroutine writeups is a table of the more common symbols used in this program.
The input data and program limits are discussed in detail in the next appendix titled "USERS MANUAL"
