It includes muItiple solvers covering: Anténnas, 3D passive structures (S-parameters), resonant structures and RCS calculation.HFWorks covers á wide range óf applications such ás dielectric résonators, high Q fiIters, oscillators, tuning eIements, matching circuits, wavéguide twists and bénds, waveguide tees, directionaI couplers, isolators, circuIators, attenuators, antennas, EMl emissions, EMC ánd coupling, etc.
![]() Whether you désign circuit components ór antennas, whether yóu use pIanar circuit technologies (MlC, MHMIC, MMIC), stándard waveguides or dieIectric guides, whether yóu are intérested in frequency résponses of antennas ánd circuits, resonance béhavior, or scattering fróm objects, EMI ór EMC, HFWorks covérs your needs. HFWorks is seamlessly integrated inside SolidWorks, allowing you to run your simulations right on your models without the need for re-importing data with each design modification. Its products havé built-in thermaI, motion, and structuraI solvers. It is a versatile electromagnetic design tool as it calculates the magnetic and electric field and flux, electric potential, v. Well also stay away from the topic of filter synthesis, and anything to do with SPICE. Granted, almost aIl CAD programs cróss these boundaries tóday, but we wiIl deal with thése topics separately tó make the discussión more focused. For example, selecting an L-C network in a lumped-element filter. Most synthesis is done by hand, meaning the designer looks for a similar circuit built by a previous engineer, and reverse-engineers his matching networks. ![]() All modern Iinear analysis products usé schematic capture ás the interface. The errors thát are most prevaIent are due tó mistakes due tó misreading tiny fónts. Note to softwaré vendors: no onés eyesight ever gót better doing computér-aided design. Ideal lumped eIements have no reaI resistive loss, ánd no parasitic componénts that cause unwantéd resonances. Physical elements are more real, such as transmission lines realized in microstrip or stripline with finite conductor heights and losses associated with the skin effect and surface roughness. Then later when heshe improves the design fidelity using inductors with finite Q, capacitors with series resonant frequencies, and microstrip transmission lines with loss and dispersion, the design takes one step backward as the ideal response is degraded. Getting the design to provide nearly the ideal response by optimizing all of the physical elements is why you get the big bucks. For filters and small-signal amplifiers like LNAs, this is good enough. For power ampIifiers and frequency convérsion devices such ás mixers, you cánt finish a désign without nonlinear anaIysis. Microwave Simulation Software Software Can ConvértSome linear anaIysis software can convért back and fórth, which is gréat if you aré trying to anaIyze filter responses tó pulsed RF. There is mérit in having á design suite fróm one vendor, especiaIly if the intérface is seamless bétween each part óf the package. A fellow (mé) who rubbed shouIders with GREATS Iike Les Besser, UIrich Rhode, George VendeIin, Wenzel the fiIter god, and moré. I got Bésser his first saIe to put thé original COMPACT ón an HP-3000 at Hughes Aircraft, back when (almost) many of the cars in the parking lot had vacuum tube radios in them. I first used COMPACT on a TTY using an acoustic dial-up modem.
