microwave spectrum การใช้

• :: Are other EM wavelengths going around in space in addition to the cosmic microwave spectrum?
• Thus, the microwave spectrum of the isopropyl cyanide has been recorded from 26.5 to 40.0 GHz.
• The microwave spectrum shows numerous lines due to spin transitions, with or without nuclear spin transitions.
• The Phoenix astronomers are scrutinizing a billion radio channels within a broad region of the microwave spectrum.
• Most satellite communications systems operate in the C, X, K a, or K u bands of the microwave spectrum.
• The microwave spectrum corresponds to frequencies between 300 MHz ( 0.3 demodulate or decode the information from that broadcaster.
• ,the detection of dicyanoacetylene in the interstellar medium has been impossible, because its symmetry means it has no rotational microwave spectrum.
• The evidence is indirect and in the form of modulations of the nonthermal microwave spectrum at approximately the expected Schumann resonance frequencies.
• The energy barrier to this inversion is 24.7 kJ / mol, and the resonance frequency is 23.79 microwave spectrum to be observed.
• Traditionally, the Federal Communications Commission has assigned microwave spectrum based on historic patterns of need and through the application / request process.
• This is true even when the molecule has a zero dipole moment and therefore has no vibration-rotation infrared spectrum or pure rotational microwave spectrum.
• Molecular constants used in determining the microwave spectrum are rotational constant B 0 = 4810.8862 MHz centrifugal distortion constant D 0 = 0.00077 MHz.
• The microwave spectrum of S 2 O has the following rotational parameters : A = 41915.44, B = 5059.07, and C = 4507.19 MHz.
• Generally speaking, metasurfaces could include some traditional concepts in the microwave spectrum such as frequency selective surface ( FSS ), impedance sheet and even Ohmic sheet.
• A 1959 paper by Philip Morrison and Giuseppe Cocconi first pointed out the possibility of searching the microwave spectrum, and proposed frequencies and a set of initial targets.
• The " water hole " part of the microwave spectrum alone _ where low background radio noise favors long-range transmission _ has about 2 billion frequencies on which to signal.
• It operated in the S band portion of the microwave spectrum, unifying voice communications, television, telemetry, tracking and ranging into a single system to save size and weight and simplify operations.
• The antenna itself often measures through a window made of foam which is transparent in the microwave spectrum in order to keep the antenna clean of dust, liquid water and ice.
• Liquid water has a broad absorption spectrum in the microwave region, which has been explained in terms of changes in the hydrogen bond network giving rise to a broad, featureless, microwave spectrum.
• In recent years there has been an explosive increase in use of the microwave spectrum by new telecommunication technologies such as wireless networks, and direct-broadcast satellites which broadcast television and radio directly into consumers'homes.
