To save time and money, HFSS 3D electromagnetic-based virtual prototyping is replacing the classical build-and-test design. By generating high accuracy, physics-based models, HFSS improves engineering productivity, reduces development time and better assures first-pass design success. The high performance electronics industry counts on HFSS™ to provide precision virtual prototypes for...

Demand for smaller, more densely packed and more powerful RF and microwave components is increasingly driving developments in a wide variety of areas, from chip packages to hand-held communication devices to phased-array antennas. In turn, the components and structures are experiencing increased levels of coupling between the electromagnetic fields...

When HFSS™ was introduced in February 1990, it created a new era in microwave design. Prior to this event, microwave design was limited to simple analyses and cut-and-try methods. With HFSS, engineers could conveniently build, analyze and refine three-dimensional (3D) microwave prototypes using their computers. For the first time,...
