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} } @article{nuteson_steer_nakazawa_mink_1999, title={Near-field and far-field prediction of quasi-optical grid arrays}, volume={47}, ISSN={["0018-9480"]}, DOI={10.1109/22.740066}, abstractNote={Field profiles, equivalent isotropic radiated power (EIRP), beamwidth, and sidelobe levels of a quasi-optical power-combining grid amplifier structure are obtained using a whole-field electromagnetic analysis of a finite structure. This is efficiently obtained using a mixed spectral- and spatial-domain method-of-moments technique. It is seen that edge effects can have a significant effect on system performance.}, number={1}, journal={IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES}, author={Nuteson, TW and Steer, MB and Nakazawa, S and Mink, JW}, year={1999}, month={Jan}, pages={6–13} } @article{nuteson_hwang_steer_naishadham_harvey_mink_1997, title={Analysis of finite grid structures with lenses in quasi-optical systems}, volume={45}, ISSN={["0018-9480"]}, DOI={10.1109/22.575583}, abstractNote={A full-wave moment-method technique developed for the analysts of quasi-optical (QO) systems is used to model finite grid structures in a lens system. This technique incorporates an electric-field dyadic Green's function for a grid centered between two lenses. This is derived by separately considering paraxial and nonparaxial fields. Results for the driving point reflection coefficient of a 3/spl times/3 and 5/spl times/5 grid in the lens system are computed and compared with measurements.}, number={5}, journal={IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES}, author={Nuteson, TW and Hwang, HS and Steer, MB and Naishadham, K and Harvey, J and Mink, JW}, year={1997}, month={May}, pages={666–672} }
