HFSS
Arbitrary 3D Full Wave Finite Element Method
Ensemble
True 3D Planar Method of Moments
HFSS applicability
Just 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 positioning
If 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?
0
Quasi Static (no radiation)
