Jun (Brandon) Choi

Assistant Professor

Electrical Engineering & Computer Science


  • Ph.D. University of California, Los Angeles

Lab/Center Affiliations:

  • Microwave lab

Research Interests:

  • Microwave circuits and systems
  • Antennas and antenna arrays
  • Periodic structures
  • Metamaterials

Current Research:

My research efforts are primarily focused in advancing practical microwave circuits using novel design techniques, including the use of periodic structures and metamaterials (also known as composite right/left-handed structures). A portion of my research interest also includes developing state-of-the-art microwave systems such as retrodirective array (RDA) that operates with arbitrary polarizations.

Courses Taught:

  • ELE722 – Microwave Filters
  • ELE723 – Microwave Transistor Amplifiers
