【Abstract】 The paper presents a survey of recent advances in microwave nonlinear circuit theory, including two general-purpose analysis techniques for microwave nonlinear circuits, separately referred to as Modified Harmonic-Balance and Frequency-Domain Continuation Intermodulation Balance Methods, and their apphcations, as well as the numerical algorithms for nonlinear equations. The present popular research proJects in this field are also discussed.更多还原
