Near-Field Millimeter-Wave Imaging via Multi-Plane MIMO Arrays
IEEE Access, 2023 Multiple-input multiple-output (MIMO) array-based millimeter-wave (MMW) imaging has broad application prospects in concealed weapons detection due to its capability of high resolution at a reasonable cost.

MODELLING AND ANALYSIS OF FUEL ASSEMBLY VIBRATIONAL MODES IN PWRS USING SIMULATE-3K [PDF]
EPJ Web of Conferences, 2021 Some of the KWU pre-KONVOI PWRs operating across Europe saw a systematic increase in the neutron noise levels over several cycles in the last decade, and subsequently, core internals’ movements, especially vibrations of fuel assemblies with specific ...

Time-domain ptychography [PDF]
, 2015 Through dedicated measurements in the optical regime we demonstrate that ptychography can be applied to reconstruct complex-valued object functions that vary with time from a sequence of spectral measurements. A probe pulse of approximately 1 ps duration,

Seismic Antiplane Response of Gaussian-Shaped Alluvial Valley [PDF]
مهندسی عمران شریف, 2021 In this study, a direct time-domain numerical approach named the half-plane Boundary Element Method (BEM) is proposed based on the half-space Green’s functions for analyzing seismic Gaussian-shaped alluvial valley subjected to propagating obliquely ...

Optomechanical time-domain reflectometry [PDF]
Nature Communications, 2018 AbstractOptical fibres constitute an exceptional sensing platform. However, standard fibres present an inherent sensing challenge: they confine light to an inner core. Consequently, distributed fibre sensors are restricted to the measurement of conditions that prevail within the core. This work presents distributed analysis of media outside unmodified,

Optical Supersymmetry in the Time Domain [PDF]
, 2019 Originally emerged within the context of string and quantum field theory, and later fruitfully extrapolated to photonics, the algebraic transformations of quantum-mechanical supersymmetry were conceived in the space realm.

Time-Domain Circuit Modelling for Hybrid Supercapacitors
Energies, 2021 Classic circuit modeling for supercapacitors is limited in representing the strongly non-linear behavior of the hybrid supercapacitor technology. In this work, two novel modeling techniques suitable to represent the time-domain electrical behavior of a ...
