A Ka-band radar is discussed for mapping surface topography of glaciers and ice sheets at a high spatial resolution and high vertical accuracy, independent of cloud cover.
A method of cleaning the mode spectra of WGM optical resonators has been devised to make such resonators more suitable for use as narrow-band optical filters.
A high-density plasma generated by microwave injection using a windowless slotted antenna has been demonstrated. Plasma probe measurements indicate that the source could be applicable for low-power ion thruster applications or ion implantation applications.
An all-permanent-magnet Electron Cyclotron Resonance (ECR), 40-cm diameter plasma source was developed. The source is capable of producing uniform ion current densities at its exit plane and very low powers
