Langmuir, 2017
Valves used to control liquid filling and draining processes from storage typically need to be actuated. Here, we show that similar flow enabling and restricting operations can be achieved through millimeter scale holes that function according to the amount of hydrostatic pressure applied without any other intervention.

Physics Today, 1950
Electromagnetic radiation, an inexhaustable natural resource, plays an extremely important part in modern technology and living. We use very short wavelength radiation, that is, x-rays, in searching for otherwise hidden defects. We use longer wavelength radiation, that is, light, to see by. We can take photographs with infrared radiation.

Millimeter/submillimeter nonlinear spectroscopy
International Journal of Infrared and Millimeter Waves, 1979The techniques of coherent transient spectroscopy have been successfully applied to the microwave and optical regions but lack of suitable sources has prevented extension to the millimeter/submillimeter wavelength region where several strong molecular transitions occur.

Millimeter-wave radiometric imaging
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The capabilities of radiometric imaging of the environment with the German Aerospace Research Establishment (DLR) modular linescanner system are demonstrated. Efficient information enhancement algorithms have been shown to improve the data interpretation and evaluation.

Superconducting bolometers for millimeter and sub-millimeter wavelengths
SPIE Proceedings, 2008We present the experimental results and a bolometer model of the voltage-biased superconducting bolometer on the low stress silicon nitride (Si3N4) membrane, developed in collaboration between the Max-Planck-Institut fur Radioastronomie (MPIfR), Bonn and the Institute for Photonic Technology (IPHT), Jena, Germany.

Millimeter-Wave Integrated Circuits
Topical Meeting on Picosecond Electronics and Optoelectronics, 1987The opportunities offered by monolithic millimeter-wave technology span radar, communications, electronic warfare, and missile seekers. These opportunities relate to size, weight, and cost reduction advantages over standard metal waveguide and hybrid integrated circuit implementations.

Josephson millimeter wave oscillators
International Journal of Infrared and Millimeter Waves, 1990This paper presents the state-of-the-art of a new class of microwave and mm-wave sources and intends to focus the attention of the microwave community on the new possibilities offered by them. Following a short introduction to the superconducting phenomena, the basic properties of Josephson tunnel junctions are presented.

Proceedings of the IEEE, 1962
The characteristics of a number of different kinds of masers are reviewed to estimate their usefulness in the region between one and a tenth millimeter. An estimate of the maximum power output for these systems is made and compared with the output to be expected from mixing two optical signals in a nonlinear dielectric and on a photocathode ...
