    collecting techniques involving telescopes to explore all different frequencies and wavelengths in space. The Square Kilometer Array will utilize radio astronomy‚ the study of radio waves‚ by linking thousands of different telescopes (both dishes and antennas) across sites in both Western Australia and South Africa to construct a giant array. Expected to be approximately fifty times more sensitive than today’s best telescopes‚ and have a survey speed of nearly a million times any telescope today‚ the

    regions where telecommunication is scarce or absent are not gifted with a connection to the World Wide Web. These are mainly due to terrestrial hurdles like dense forests‚ deserts‚ mountains‚ etc. These restrict construction of cell towers‚ radio antennas and other connectivity based infrastructure. This is a problem‚ isn’t it? To eliminate this problem‚ straight out of Google X lab‚ comes another ambitious project to bring everyone up to power with the Internet. Named Project Loon‚ it focuses on

    capacitors and frequency-dependent inductors. Because stubs take on reactive properties as a function of their electrical length‚ stubs are most common in UHF or microwave circuits where the line lengths are more manageable. Stubs are commonly used in antenna impedance matching circuits and frequency selective filters. Smith charts can also be used to determine what length line to use to obtain a desired reactance. In their simplest form‚ stubs that are some multiple of a quarter wavelengths are used

    SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

    Response of the Organism: Hyalella azteca Chemosensory organs in many crustaceans including Hyalella azteca allow them to locate food and mates while entirely avoiding predators. When detecting environmental changes such as the change in chemicals such as salinity‚ many amphipods have tiny hair-like organs containing sensory cells called sensilla (Hallberg‚ 2011). These chemosensory olfactory receptors are virtually found on many parts of the crustacean body including antennae‚ mouthparts and tips

    2.9 Erbium Doped Fiber Laser The EDFLs can operate in several wave-length regions‚ ranging from visible to far infrared. The 1.55 region has attracted the most attention because it coincides with the low-loss region of silica fibers used for optical-communications [14]. The erbium absorption line that best matches with available high power pump diodes is in the 980 regime. At this wave-length‚ the absorption cross section of erbium is so low that an excessive amount of fiber would be required for

Studies on the enhancement of transition rates in solid-state systems consequently focused on coupling emitters to photonic cavities with high quality factors or to metallic nanoscale resonators. In the latter case‚ nanogap metallic antennas supporting lossy plasmon polaritons feature broad resonances whose low quality factors are compensated by high field confinement‚4–6 making them one of the most widely studied plasmonic devices for enhancing the electric dipolar decay rates
