Research Interests Vacuum Electron Devices

I am interested in a variety of basic and applied physics related to terahertz/millimeter-wave generation and the interaction of waves with electron beams and plasmas

Photonic Band Gap Structures

• High-frequency accelerator cavities based on photonic band gap (PBG) technology
• Overmoded PBG cavities for vacuum electron devices

High-Power Millimeter Waves

• Formation of self-organized plasma arrays in millimeter-wave breakdown
• Scattering and diffraction of millimeter waves from plasma

Terahertz and Millimeter Wave Sources

• 110 GHz, 1.5 MW gyrotron oscillator
• 370 GHz dielectric wakefield radiation source
