Research Interests
Dr. Temkin's research interests encompass a variety of fields of basic and applied physics, with major emphasis on coherent sources of infrared and millimeter waves and their applications. Both experimental and theoretical research activities are undertaken.

Major research projects include:

Electron Cyclotron Maser/Gyrotron:
Experimental and theoretical research on high frequency (50 - 600 GHz), high power (up to 1 MW) gyrotrons and on the application of gyrotrons to plasma heating, radar, and plasma diagnostics.

High Gradient Acceleration:
High gradient electron accelerators capable of operation at gradients above 100 MeV/meter. Novel sources of high power microwaves and novel structures for achieving high gradient acceleration. Laser-photocathode driven RF-guns for use as injectors into high gradient accelerator structures.

Photonic Bandgap Structures:
Novel photonic bandgap structures for use in active devices, including vacuum electron devices and accelerators, and in passive devices such as transmission lines and beam combiners.

Quasi-Optical Antenna Research:
Theoretical and Experimental research on quasi-optical antennas capable of transforming high order waveguide modes into Gaussian beams in free space for microwave transmission and launching applications.

Free Electron Lasers:
Novel concepts for the free electron laser including electromagnetic wave wigglers and microwigglers. Application of the FEL to radar, plasma heating and biomedicine.

Plasma Heating:
Heating of plasmas at electron cyclotron resonance using high power millimeter wave sources such as gyrotrons or FELs. Techniques for transmitting, polarizing and launching high power electromagnetic radiation

.High Magnetic Field, Nuclear Magnetic Resonance (NMR):
Dynamic nuclear polarization using combined NMR and electron spin resonance (ESR) at high magnetic fields (5 - 10T) for enhanced imaging. Electron paramagnetic resonance (EPR) and spin resonance spectroscopy and spin echo at high magnetic fields.
