Most of the work in the far field is carried out in the microwave region
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 .
Mueller, "Background loss of amorphous dielectrics in the high frequency and microwave region
," Transactions of the Faraday Society, vol.
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 , free space , open-ended coaxial probe , 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.
