ECE Optics and Photonics Lab - Anechoic Chamber

Applied electromagnetics and acoustics

Electromagnetic and acoustic waves are at the heart of countless innovative technologies and scientific tools for applications in wireless communications, remote sensing, Internet of Things, wireless networks, medical imaging, healthcare, security, and defense. UW-Madison ECE faculty and students in this area are known internationally for their research advances in:

  • Antennas
  • Phased-array systems
  • Metamaterials
  • Microwaves/millimeter-wave/THz systems
  • Wave propagation through media and channels
  • High-power microwave sources and amplifiers
  • Vacuum electronics
  • Wireless power transfer
  • Computational electromagnetics
  • RF/microwave/ultrasonic medical imaging and remote sensing
  • Nondestructive testing
  • Therapeutic and diagnostic applications of RF/microwaves/acoustics
  • Bioelectromagnetics
  • Ab initio calculations and measurements of dielectric properties of materials at the nanoscale
  • Micron-sized particle accelerators

Next-gen research from inside our anechoic chamber

This photograph shows a near-field antenna measurement system used for measuring the radiation properties of antennas operating in the 600 MHz to 18 GHz frequency band. In the center of the photograph, you can see a scaled model of a midsize aircraft with several antennas mounted on it. Scaled model measurements are often used to characterize the radiation properties of antennas mounted on large structures such as aircrafts, ships, and vehicles at an early design and optimization stage.
