HFSS acts as a virtual laboratory, allowing computer aided design work without the need for hardware. This capability for first pass designs, avoids the time and expense of multiple design-build-test-and repeat cycles. Iterations and optimization are done directly, resulting in components that work as predicted with the first prototype. If your need involves electromagnetic fields, there's a good chance it can be handled with HFSS. I have been using HFSS since it first came out in the early 90's. My unique combination of theoretical and hardware experience, coupled with the computer "virtual laboratory", positions me to respond quickly to a wide variety of requirements, as indicated by my many satisfied Clients.
