Research on terahertz wave transmission through plasma is significant for researches on plasma itself and transmission discipline of terahertz wave through plasma. It is possible for plasma with suitable density to be an available stealth outerwear for plane or missile in THz waveband. In this paper, plasma is gotten by ionizing inert gases such as argon and helium gases with pulsed high alternating...
A novel portable concentrated sunlight electric generator is described. It consists of two 2×3 point focus Fresnel lens parquets which focus sunlight onto 12 high efficiency triple junction solar cells mounted on two aluminum backed circuit boards. These lens parquets along with a linear tracker drive can be stowed in a case roughly the size of a notebook computer with dimensions of 11"×14.8"×1...
JX Crystals Inc is developing a class of compact portable solar generators using commercially available 32% efficient multijunction solar cells. Three different sized solar generators with nominal power ratings of 12 W, 36 W and 75 W are described. The high solar cell efficiency will allow all three units to be small, portable, and light weight. (For example, the 12 W generator will fit in a pocket...
JX Crystals' 3-sun PV mirror modules have now been operating in four separate systems in the field for up to 2 years. Two post-mounted 2-axis tracking arrays of 12 modules each were installed at the Shanghai Flower Park in April of 2006. Then 672 modules were installed in a 100 kW array on N-S horizontal beam trackers at the Shanghai Flower Port in November of 2006. Finally, sets of 4 modules were...
