Influence of Channel Count and Array Sparsity on the Detection Performance of 4D Imaging Radars

open access: yesIEEE Journal of Microwaves
Separability, detection capability, and height estimation performance are key measures of high performance 4D imaging radars. While many different sensors have been presented in recent years, no sensor-independent comparison of the performance achievable

Spatially‐Resolved Coherence of Organic Molecular Spins at Room‐Temperature

open access: yesAdvanced Functional Materials, EarlyView.
Molecular spin qubits are emerging as a promising quantum sensing technology. This paper studies the variation in coherence and sensitivity in both crystalline and thin‐film samples by combining microscopy and room temperature optically detected coherent control.

Rapid microwave processing of epoxy nanocomposites using carbon nanotubes [PDF]

open access: yes, 2013
Microwave processing is one of the rapid processing techniques for manufacturing nanocomposites. There is very little work focussing on the addition of CNTs for shortening the curing time of epoxy nanocomposites. Using microwave energy, the effect of CNT

UAV-Based SAR-Imaging of Objects From Arbitrary Trajectories Using Weighted Backprojection

open access: yesIEEE Journal of Microwaves
Synthetic aperture radars (SARs) based on uncrewed aerial vehicles (UAVs) are advantageous in comparison to existing airborne systems. Apart from cost, their main advantage is the flexibility of their flight path.

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame

open access: yesAdvanced Functional Materials, EarlyView.
High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Mechanical and Structural Properties of Microwave Sintered Tin-Copper-Antimony Alloys [PDF]

open access: yes, 2009
Tin-copper-antimony (pewter) alloys have been traditionally produced by a casting process which consumes large amounts of energy, time and as a result is expensive. This research aims to investigate the possibilities of implementing powder metallurgy for

Improving Microwave Cooking Performance by Source Phase Shifting [PDF]

open access: yes, 2014
Microwave cooking is rapid, but non-uniform. The effects of thermal non-uniformity are hot spots, cold spots and microbiological safety issues. An approach, based on phase shifting of two microwave generators, is proposed in order to attain a more ...
