In this paper, a novel design of near-field dipole antenna sensor array for breast tumor detection is presented. The proposed consists four electrically small antennas fed by single port. Due to the proven fact that tumors have higher dielectric properties than surrounding normal tissues, utilized detecting evaluating variations sensor’s response two cases, and abnormal, tissues. A simulation s...
A small forbidden gap matched to low-energy photons (meV) and a quasi-Dirac electron system are both definitive characteristics of bilayer graphene (GR) that has gained it considerable interest in realizing a broadly tunable sensor for application in the microwave region around gigahertz (GHz) and terahertz (THz) regimes. In this work, a systematic study is presented which explores the GHz/THz ...
Recently there has been an increasing interest in the classification of edible oils as an effective means to examine authenticity and to detect possible adulteration of virgin olive oils with seed oils or low-quality olive oils. Classical methods based on gas chromatography (GC) and high-performance liquid chromatography (HPLC) are too expensive for widespread industrial use and require samples...
Synthetic Aperture Radar (SAR) is one of the active microwave sensor that can capture the Electromagnetic Radiation signals of the physical objects. The ability of the microwave sensor to work in day and night is one of the major advantages and very useful in this technique. The capturing of scattered signals from SAR by using polarimetric process is applied to analyze distribution of various o...
The Landsat-8 satellite of the Landsat Data Continuity Mission was launched by the National Aeronautics and Space Administration (NASA) in April 2013. Just weeks after it entered active service, its sensors observed activity at Paluweh Volcano, Indonesia. Given that the image acquired was in the daytime, its shortwave infrared observations were contaminated with reflected solar radiation; howev...
Arctic sea ice motion for the period from October 1999 to March 2000 derived from QuikSCAT and special sensor microwave/imager (SSM/I) data using the wavelet analysis method agrees well with ocean buoy observations. Results from QuikSCAT and SSM/I are compatible when compared with buoy observations and complement each other. Sea ice drift merged from daily results from QuikSCAT, SSM/I, and buoy...
