Microwave Imaging for Brain Stroke Monitoring [PDF]
The capability of microwaves to penetrate an object as interact differently with each of its elements, allows Microwave Imaging (MWI) technologies to be used in a myriad of fields and applications to "see-through" an object in a non-invasive approach. For instance, in the biomedical field, the scattered signals from cancer lesions, blood accumulation ...

Sensitivity Study of the Microwave Spiralimetric Imaging [PDF]
The use of the spiral modes-electromagnetically related to the orbital momentum of the photons- at microwave frequencies for imaging purposes is studied and some preliminary numerical and experimental results for basic canonical geometries are presented and ...

Near-Field Microwave Microscopy of Materials Properties [PDF]
Near-field microwave microscopy has created the opportunity for a new class of electrodynamics experiments of materials. Freed from the constraints of traditional microwave optics, experiments can be carried out at high spatial resolution over a broad frequency range.

Indirect Microwave Holography and Through Wall Imaging [PDF]
In this paper, a review of indirect microwave holography for through-wall imaging is presented. Indirect microwave holography is an imaging technique, enabling the complex object scattered fields (amplitude and phase) to be mathematically recovered from intensity-only, scalar microwave measurements. By removing the requirement to use vector measurement

Non-Invasive Imaging Method of Microwave Near Field Based on Solid State Quantum Sensing [PDF]
In this paper, we propose a non-invasive imaging method of microwave near field using a diamond containing nitrogen-vacancy centers. We applied synchronous pulsed sequence combined with charge coupled device camera to measure the amplitude of the microwave magnetic field.

Perfect imaging without negative refraction for microwaves [PDF]
We demonstrate perfect imaging in Maxwell's fish eye for microwaves. Our data show that the field of a line source is imaged with subwavelength resolution over superwavelength distances, provided the field is allowed to leave through passive outlets that play the role of a detector array in imaging.

Large-aperture computational single-sensor microwave imager using 1-bit programmable coding metasurface at single frequency [PDF]
The microwave imaging based on inverse scattering strategy holds important promising in the science, engineering, and military applications. Here we present a compressed-sensing (CS) inspired large- aperture computational single-sensor imager using 1-bit programmable coding metasurface for efficient microwave imaging, which is an instance of the coded ...

Fast Algorithm of High-resolution Microwave Imaging Using the Non-parametric Generalized Reflectivity Model [PDF]
This paper presents an efficient algorithm of high-resolution microwave imaging based on the concept of generalized reflectivity. The contribution made in this paper is two-fold. We introduce the concept of non-parametric generalized reflectivity (GR, for short) as a function of operational frequencies and view angles, etc.
