Microwave imagingNear-fieldNondestructive evaluationProbeSubsurface imagingIn this paper, a microwave microscope for nondestructive evaluation of biological tissues using a near-field probe is described. For this purpose, a near-field probe to obtain microwave image with high resolution at 18.6 GHz is ...
Near-Field Imaging of the Photocurrent Induced by Light on Boron-Implanted Silicon We report near-field photocurrent (PC) measurements performed on boron-implanted silicon and acquired at λ = 633, 1330, 1550 nm corresponding to photon en... V Marocchi,A Cricenti,P Perfetti,... - 《Physica...
Antennas capable of sending and receiving ultra-wideband pulses are required for radar-based microwave breast imaging.This article describes a TEM horn antenna designed to operate over a 2-12 GHz band with specific radiated near-field characteristics. Simulations and experimental measurements are presente...
The most important advantage of the proposed imaging setup is that it eliminates the need for background (or baseline) measurements, thus simplifying the system calibration. Also, it is proven that at least two-fold improvement in the spatial resolution can be achieved in near-field imaging ...
A protocol to measure the system fidelity of a two-antenna UWB system for near-field microwave imaging is presented. It consists of identical transmission and reception antennas that are highly directive and work without coupling medium in tissue sensing applications. System fidelity is evaluated with...

Dielectric director for near-field microwave imaging This paper presents a parametric study of selected parameters that define the director used to improve the radiation behavior of a balanced antipodal Vivaldi antenna. The near-field radiation distortion and intensity are of interest. The ... Bour...
They replace the plane (or spherical) wave assumption in the previous holographic methods and enable accurate near-field imaging results. Here, we prove that both the incident field and Green's function can be obtained from a single numerical simulation. This eliminates the need for optimization-...
The microwave properties of nano-scale structures are important in a wide variety of applications in quantum technology. Here we describe a low-power cryogenic near-field scanning microwave microscope (NSMM) which maintains nano-scale dielectric contrast down to the single microwave photon regime, up...
