The design of the program is intended to offer flexibility without sacrificing efficiency. Recent developments in object-oriented techniques and in C++ compilers are used to obtain a flexible and robust system ideally suited to the development of a global modeling strategy for the integration of circuit, field, thermal, and mechanical analyses. The simulation of spatial power combining systems is used as a vehicle to illustrate the architectural developments of the system.}, number={3}, journal={INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING}, author={Christoffersen, CE and Mughal, UA and Steer, MB}, year={2000}, month={May}, pages={164–182} }

The recent development of the local reference node concept coupled with steady-state and transient analyses using state variables allows the incorporation of unrestrained EM modeling of microwave structures in a circuit simulator. A strategy implementing global modeling of electrically large microwave systems using the circuit abstraction is presented. This is applied to the modeling of a quasi-optical power-combining amplifier.}, number={6}, journal={IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES}, author={Steer, MB and Harvey, JF and Mink, JW and Abdulla, MN and Christoffersen, CE and Gutierrez, HM and Heron, PL and Hicks, CW and Khalil, AI and Mughal, UA and et al.}, year={1999}, month={Jun}, pages={830–839} }
