Journal ArticleDOI
Enhanced detection limit by dark mode perturbation in 2D photonic crystal slab refractive index sensors
TL;DR: A new layer architecture is created resulting in electric field enhancement at the interface between the slab and sensing regions, and spectral sensitivity of >800 nm/RIU, that is, >0.8 of the single-mode theoretical upper limit of spectral sensitivity.
Journal ArticleDOI
Imaging brain activity during seizures in freely behaving rats using a miniature multi-modal imaging system
Iliya Sigal,Margaret M. Koletar,Dene Ringuette,Raanan Gad,Melanie A. Jeffrey,Peter L. Carlen,Bojana Stefanovic,Ofer Levi +7 more
TL;DR: A miniature label-free imaging system for monitoring brain blood flow and blood oxygenation changes in awake, freely behaving rats and is applied to monitoring neurovascular coupling during drug-induced absence-like seizures 6 weeks following the craniotomy.
Journal ArticleDOI
Laser speckle contrast imaging with extended depth of field for in-vivo tissue imaging.
Iliya Sigal,Raanan Gad,Antonio M. Caravaca-Aguirre,Yaaseen Atchia,Donald B. Conkey,Rafael Piestun,Ofer Levi +6 more
TL;DR: This work presents the first demonstration of the Laser Speckle Contrast Imaging (LSCI) technique with extended depth of field (DOF) technique, showing improved ability to image flow in a larger number of vessels simultaneously.
Journal ArticleDOI
Observation of magnetically induced transparency in a classical magnetized plasma.
TL;DR: This work reports the first demonstration of magnetically induced transmission in an opaque magnetized plasma, where the transverse-periodic magnetic field uncouples the right-hand electromagnetic wave from interacting with plasma electrons, rendering the plasma band-stop transparent.
Journal ArticleDOI
High power microwave source for a plasma wakefield experiment
G. Shafir,A. Shlapakovski,M. Siman-Tov,Yu. P. Bliokh,J G Leopold,S. Gleizer,Raanan Gad,V. V. Rostov,Ya. E. Krasik +8 more
TL;DR: In this paper, the results of the generation of a high-power microwave (∼550 MW, 0.6 GHz) beam and feasibility of wakefield-excitation with this beam in under-dense plasma are presented.
