An object-oriented microwave circuit simulation environment is described. T
he design of the program is intended to offer flexibility,without sacrifici
ng efficiency. Recent developments in object-oriented techniques and in C+ compilers are used to obtain a flexible and robust system ideally suited t
o the development of a global modeling strategy for the integration of circ
uit, field, thermal, and mechanical analyses. The simulation of spatial pow
er combining systems is used as a vehicle to illustrate the architectural d
evelopments of the system. (C) 2000 John Wiley & Sons, Inc.
