Journal ArticleDOI
Manipulating Interfacial Thermal Conduction of 2D Janus Heterostructure via a Thermo‐Mechanical Coupling
TL;DR: In this article , the phonon transport in 2D Janus transition metal dichalcogenide (TMD) semiconductor materials has been investigated for thermal management of 2D devices with single-atom thickness.
Journal ArticleDOI
A Uniform Diffraction Tomographic Imaging Algorithm for Near-Field Microwave Scanning Through Stratified Media
Kai Ren,Robert J. Burkholder +1 more
TL;DR: In this paper, a 2D near-field uniform diffraction tomographic (UDT) imaging algorithm is formulated to generate images of targets embedded in a layered structure, where the large argument is not the depth, which is not appropriate for near field imaging.
Journal ArticleDOI
A Pole-Extraction Algorithm for Wall Characterization in Through-the-Wall Imaging Systems
TL;DR: In this article, a novel algorithm based on pole extraction and wall reflection coefficients is presented to accurately estimate the essential parameters of a multi-layered wall in focused through-the-wall imaging (TWI).
Journal ArticleDOI
Identification of Hidden Objects in Layered Media With Shadow Projection Near-Field Microwave Imaging
Kai Ren,Robert J. Burkholder +1 more
TL;DR: A shadow projection approach for near-field microwave imaging is developed to distinguish the size and shape of objects embedded in layered media and is demonstrated by 3-D numerical simulations of air voids in a dense dielectric slab.
Journal ArticleDOI
A 3-D Uniform Diffraction Tomographic Algorithm for Near-Field Microwave Imaging Through Stratified Media
TL;DR: In this article, the authors extended the 2D scalar uniform diffraction tomographic (UDT) algorithm to a fully vector 3D solution involving the dyadic Green's function for the layered media, the polarization of the gain pattern of the probe antenna, and the stationary phase evaluation of a 2D spectral integral.
