Passive sensing around the corner using spatial coherence

M Batarseh, S Sukhov, Z Shen, H Gemar… - Nature …, 2018 - nature.com
When direct vision is obstructed, detecting an object usually involves either using mirrors or
actively controlling some of the properties of light used for illumination. In our paradigm, we …

On the inverse problem of source reconstruction from coherence measurements

A Beckus, A Tamasan, A Dogariu, AF Abouraddy… - JOSA A, 2018 - opg.optica.org
We consider an inverse source problem for partially coherent light propagating in the
Fresnel regime. The data are the coherence of the field measured away from the source …

A ceramic-based microwave sensor for both permittivity and permeability characterization of materials

X Lu, Q Tan, T Zhang, H Kou, L Zhang… - Journal of Physics D …, 2020 - iopscience.iop.org
In this study, a novel microwave microstrip sensor is proposed for the simultaneous
characterization of a material's permittivity and permeability. The electric permittivity and …

Departure from the Babinet principle in metasurfaces supported by subwavelength dielectric slabs

G Biasiol, S Zanotto - Optics Letters, 2020 - opg.optica.org
Symmetry principles and theorems are of crucial importance in optics. Indeed, from one side,
they allow obtaining direct insights into phenomena by eliminating unphysical …

Passive Scene Reconstruction in Non-line-of-sight Scenarios

A Beckus - 2020 - stars.library.ucf.edu
Locating and identifying hidden objects can prove critical in applications ranging from
military reconnaissance to emergency rescue. Although non-line-of-sight (NLOS) …
