concept is known as Microwave Power transmission (MPT). This paper is mainly concentrated on : i) The most popular concept known as Tesla Theory‚ ii) The microwave power transmission(MPT) called Solar power satellite‚ and iii) The highly efficient fiber lasers for wireless power transmission. The output microwave power ranges from 50 W to 200 W at 2.45 GHz.

from light bulbs and LEDs. 3. Laser – Acronym for light amplification by stimulated emission of radiation. The laser produces a coherent source of light with a narrow beam and a narrow spectral bandwidth (about 2cm). Lasers in fiber optics are usually solid-state semiconductor types. Lasers are used to provide the high-powered‚ tightly controlled light wavelengths necessary for high-speed‚ long-distance optical fiber transmissions. 4. Output Pattern – LED and laser semiconductors used in fiber-optic

Rather than shining a monochromatic beam of light at the sample‚ this technique shines a beam containing many frequencies of light at once‚ and measures how much of that beam is absorbed by the sample. Next‚ the beam is modified to contain a different combination of frequencies‚ giving a second data point. This process is repeated many times. Afterwards‚ a computer takes all these data and works backwards to infer what the absorption is at each wavelength The beam described above is generated by

My disorder is Birt Hogg Dubes Syndrome. Birt Hogg Dubes Syndrome is a rare disorder that effects the skin and lungs and increases the risk of some types of tumors. These tumors are painful and very difficult and almost impossible to get rid of. The main cause of this disorder is inheritance of a dominant gene pattern resulting in a gene mutation. The symptoms of this disorder are bumpy like tumors on your skin and lungs. Some tests to diagnose this disorder include seeing bumps on skin or lungs
