Electromagnetic Modeling
Surface currents and radiation pattern for a microstrip antenna on an infinite ground plane, modeled with the Method of Moments.
Historically, many Electronics Systems and Robotics Department projects have relied on the use of electric, magnetic, or electromagnetic technologies as part of solutions for clients. While Southwest Research Institute (SwRI) engineers often provide quality solutions using standard design techniques, some problems are best solved with the aid of computer modeling.
Emilio Martinez, Staff Engineer
Staff members employ numerous tools, including commercial software and software written at SwRI, when applying CEM. These tools incorporate a variety of methods, primarily:
- Method of Moments
- Finite Element Method
- Finite-Difference Time-Domain Method
- Hybrid methods, including UTD and PO
Electromagnetic Modeling Technical Strengths
- Department personnel use computational electromagnetics
(CEM) to test designs in areas such as:
- Magnetostatics (e.g., magnet design and magnetic resonance)
- Magneto-quasi-statics (e.g., AC induction fields)
- Antennas
