Proposed novel imaging technique will provide all weather high-resolution imaging and recognition capability for RF/Microwave signals with good penetration through highly scattered media: fog, snow, dust, smoke, even foliage, camouflage, walls and ground. Image resolution in proposed imaging system is not limited by diffraction and will be determined by processor and sampling frequency. Propose...

Modeling the demand for a portfolio of products as a function of price is a classical problem in operations with applications in retail and revenue management. Retailers have started to change their products’ prices frequently giving them access to vast amounts of data on aggregate sales at different price configurations. According to a recent Wall Street Journal article, the price of a microwa...

In this paper, we have presented a microwave scattering analysis from multiple human head models. This study incorporates different levels of detail in the human head models and its effect on microwave scattering phenomenon. Two levels of detail are taken into account; (i) Simplified ellipse shaped head model (ii) Anatomically realistic head model, implemented using 2-D geometry. In addition, h...

The detection of breast cancer in its early stage is a developing research field that can rescue the women affected by cancerous tissues. A modest and skilful approach in microwave imaging (MWI) for data inversion is proposed. MWI in medicinal applications has been famous in last two decades and presently it is using for the detection of breast cancer. Medical imaging by microwave technology ha...

A massive photon possesses a longitudinal polarization mode absent in its massless counterpart. Transverse and modes follow different dispersion relations, the latter being much less attenuated than former when passing through conductor, suggesting possibility of isolating by shining intense light on conducting wall. We calculate transmission rates for normal incidence upon semi-infinite medium...

PURPOSE Numerical study of microwave imaging and microwave-induced thermoacoustic imaging utilizes finite difference time domain (FDTD) analysis for simulation of microwave and acoustic interaction with biological tissues, which is time consuming due to complex grid-segmentation and numerous calculations, not straightforward due to no analytical solution and physical explanation, and incompatib...

A simple and practical microwave frequency-shifting technique based on a general temporal self-imaging (GTSI) effect in optical fiber is proposed, formulated, and experimentally demonstrated. The proposed technique can be applied to an arbitrary periodic microwave signal (e.g., a microwave tone) and provides unparalleled design flexibility to increase the frequency of the input microwave signal...
