The current generation of field simulation codes are powerful design tools that are highly accurate and can solve small to moderately sized problems. For multi-wavelength structures the options are limited. Examples of application areas where one would find such structures include Rotman lens design, IC package design, and electromagnetic compatibility simulation. As the demand for higher performance designs increases in these industries the need for a CAD software package that can analyze these geometries also increases. In addition to being able to simulate larger geometries it is also important that such a tool be easy to use with a user friendly GUI and have robust model translation. We purpose to extend the analysis capabilities of Ansoft HFSS to be able to simulate large multiple wavelength structures. HFSS has a user friendly interface and accurate simulation engine. We purpose to enhance that engine to allow it to efficiently simulate both electrically large and small geometries and to implement further improvements to the user interface and model translation tool.
Benefits: An effective multi-wavelength CAD tool would be of enormous benefit to researchers and designers involved in the study or design of Rotman lens antennas, IC packaging and electromagnetic compatibility.
