microwave region

microwave region

Commonly, that region of the radio spectrum between approximately 1000 MHz and 300,000 MHz. Corresponding wavelengths are 30 cm to 1 mm. The limits of the microwave region are not clearly defined, but in general they are considered to be the region in which the radar operates. See electromagnetic spectrum.

Most of the work in the far field is carried out in the microwave region [5-8].
First, we review studies of breast tissue properties in the microwave region. Microwave breast imaging could be possible due to the difference in dielectric properties between malignant tissue and normal breast tissue.
As for the defected ground structure (DGS), it can be regarded as "electromagnetic bandgap" (EBG) structure in the microwave region [8, 9] and the structure is realized by etching periodic or nonperiodic patterns on the metallic layer in order to create extra transmission zeros.
Tender issueFollowing the successful completion of a GSP study titled "Use of Spectral Information at Microwave Region for Numerical Weather Predictiona this follow-on activity has the objective to design build and successfully flight-test a Microwave Hyperspectral Instrument Demonstrator for future campaign use.
Optical, thermal infrared and passive microwave regions of the electromagnetic spectrum were exploited in this study i.e., NIR, Red and blue bands for the Enhanced Vegetation Index (EVI) in optical domain, thermal Infrared band for Land Surface Temperature (LST) and passive microwave region for soil moisture (a level 3 product of AMSR-E) in conjunction with rain gauge 24 hours data.
When the device was switched on, electrons flowed single-file through each double quantum dot, causing them to emit photons in the microwave region of the spectrum.
in the microwave region. That absorber consisted of an array of split ring resonators (SRRs) and a resistive sheet to absorb EM energy of the incident wave at the resonance frequency [1].

The refractive indices inside and outside the object are 3.5 (silicon in microwave region) and 1 (air), respectively.
The most widely used techniques in the microwave region are: cavity resonator [3], free space [4], open-ended coaxial probe [5], and transmission-line [6-9].
Many digital communications and radar applications today require demodulation and analysis of wideband signals in the microwave region. While in some applications, this task can be accomplished using a modern wideband oscilloscope to directly digitise signals for analysis, the Agilent PXA provides a more convenient and economical solution.
A team at Rensselaer Polytechnic Institute has found a new way to generate radio waves of the frequencies between infrared and the microwave region, opening new possibilities for detecting chemical weapons, explosives and even drugs from 60 feet away.
