Website: SARA, Inc.

Since 1989, SARA, Inc. has been an innovator in electrical, electromagnetics, and acoustics R&D for both defense and commercial applications. For more than 20 years we have employed COMSOL Multiphysics® in our research and engineering work in support of organizations, institutions, and businesses large and small. Our clients and research partners include every branch of the U.S. armed forces, major aerospace companies, universities, NASA, U.S. Department of Energy laboratories, and commercial organizations, among others. SARA products cover a wide range of advanced solutions, including high-power microwave (HPM) sources, electromagnetic pulse (EMP) test equipment, shielded enclosures, and our patented Terrestrial Acoustic Sensor Array (TASA) Detect and Avoid (DAA) systems.

Areas of Expertise

  • Custom antennas and waveguide components, especially for high-peak powers
  • Compact high-voltage, pulsed power, and high-power microwave components
  • RF & EM coupling and shielding and time-domain pulsed fields
  • Electrostatics, magnetic field coils, and near-field coupling
  • Time-domain thermal analysis, heat sink design, and multiphysics phenomena such as Joule heating
  • Structural mechanics, materials, and fatigue
  • Acoustics and vibration
  • Fluid flow
  • CAD model import, such as importing geometry from SOLIDWORKS® into COMSOL Multiphysics®
  • Creating advanced geometries using the Design Module, an add-on to COMSOL Multiphysics®
  • Prototyping and proof-of-principle tests

Our Focus

When creating COMSOL models and simulations to address your unique design challenges, our High-Power Electromagnetics (HPEM) and Advanced Perception Threat Awareness (APTA) teams are able to draw upon the vast knowledge base of SARA’s scientists, engineers, physicists, and distinguished technical fellows. SARA is equipped to access and apply uniquely specialized knowledge provide solutions — that work! — to your specific applications.

Consultant Contributions


The first edition of COMSOL News shared SARA’s use of COMSOL Multiphysics® to design and optimize a twist-reflector antenna in the article “Simulations Key to Non-Lethal Microwave Weapon”.

Application Exchange:


SARA has employed COMSOL Multiphysics® with much success in the design of leaky-wave antennas:
