Wideband Printed Antenna Elements for Through- Wall Microwave Imaging Applications
In this paper, the probefed stacked patch antenna and the E-shaped patch with a parasitically coupled selfcomplementary element (ESCE) are designed and analyzed in wall proximity in order to study the effects of various wall parameters on the antenna’s radiation characteristics. In particular, the effect of different wall-antenna separations as well as different wall material properties on impe...
متن کاملAn Improved Time-Reversal-Based Target Localization for Through-Wall Microwave Imaging
Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is applied to detect and localize a target obscured by a brick wall using a numerically generated data. Regarding this, i...

متن کاملHolographic microwave imaging for medical applications
This paper presents a new 2D holographic microwave imaging array (HMIA) technique for medical imaging applications. The HMIA technique has been applied to early stage breast cancer detection and brain stroke detection. Computer models are developed to demonstrate the feasibility of detecting and localizing small brain strokes within a 2D numerical head model and breast tumours within a 3D numer...
متن کاملPolarization insensitive imaging through polarization gratings.
Liquid crystal polarization gratings exhibit high diffraction efficiency (approximately 100%) in thin material layers comparable to the radiation wavelength. We demonstrate that they can be combined for polarization-insensitive imaging and optical switching applications. A pair of closely spaced, parallel oriented, cycloidal polarization gratings is capable of canceling the diffractive property...
