Recent advances in high speed photodetector and microwave receiver technology make microwave frequency optical heterodyning an attractive approach for the detection of a number of coherent Raman and Brillouin scattering experiments. We have therefore analyzed the sensitivity of microwave frequency optical heterodyne receivers. Experimental tests on a visible wavelength receiver operating at 13....

China first lunar probe satellite “Chang’E-1(CE-1)” was successfully launched on Oct.24th, 2007 and reached the lunar polar working orbit with 200km altitude from lunar surface on Nov.7th . CE-1 satellite had been working normally during more than one year life time and has collected huge scientific data and images. Chang’E-1 microwave sounder (CELMS) is a four-frequency microwave radiometer. T...
Hyperhidrosis is the production of sweat above and beyond normal physiological needs, regardless of the ambient temperature, and it affects > 4% of the population. In addition, a poll showed up to 21% of the population is bothered on a daily basis by their amount of underarm sweating. Despite the large number of patients who suffer from hyperhidrosis, there are relatively few effective nonsurgi...
The objective of this paper is threefold: 1) To present a working methodology for the combined use of modeling technology and microwave remote sensing measurements in the assessment of attenuation of electromagnetic waves by the vegetation cover; 2) To illustrate this methodology with computer calculations of the attenuation for various soil-plant formations; 3) To give a perspective of the dev...
Scale up of microwave sintering for high temperature stable non-oxide ceramics, such as SiC, Si3N4, and dispersion ceramics, like SiC-MoSi2 is still difficult, mainly because of lack of an affordable equipment. For air atmosphere sintering different furnaces were developed, like e.g., gas-microwave hybrid heated tunnel kilns [1] or microwave sintering using an adiabatic casket in tunnel kilns [...
