各种结构位置HFSS PositioningHigh-Frequency Products HFSS Arbitrary 3D Full Wave Finite Element Method Ensemble True 3D Planar Method of MomentsHFSS applicabilityJust a rule of thumb…. 0.01 λ < geometry length geometry volume < 100 λ3 Results in terms of S and Z parameters, EM fields in the geometry and radiated fieldsHFSS positioningIf geometry < 0.1 λ and little radiation use parameter extractor + schematic capture Voltages, currents, R,L,C,G, circuit simulation If geometry very large use optical methods like Physical Optics, GTD, ray tracing Else use HFSSWhen do we use quasi-static techniques? When do we use full-wave techniques?0Quasi Static (no radiation)λ/10Gray region Full Wave (including radiation)Measure the size of the interconnect in units of wavelength! (If we……
