The numerical solution of antenna and scattering problems

It is pointed out that numerical solutions of electromagnetic boundary-value problems deserve to receive greater emphasis, particularly those arising in practical applications. Numerical methods of solution can also be of great help in theoretical studies where suitable analytical solutions are difficult to obtain. By using a certain fundamental integral equation for the electromagnetic field, it is shown that many problems can be reduced to the solution of standard types of integral equations for which numerical techniques of solution already exist.
