We designed AlGaAs all-dielectric nanoantennas with magnetic dipole resonance at near-infrared wavelengths. These devices are shaped as cylinders of 400nm height and radii varying from 175 nm up to 230 nm. We analyzed volume χ(2) nonlinear effects associated to a magnetic dipole ... Per saperne di più
In a magnetic resonance imaging (MRI) system, it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires a coupling between the nuclei and a source of radio frequency (RF) power using a transmitter. To receive a meaningful signal, we also need ... Per saperne di più
High-power couplers (both coaxial and ridge waveguide type) at UHF frequencies are presently under development for the Low Energy High Intensity Proton Accelerator (LEHIPA) project and 1 GeV proton accelerator at Bhabha Atomic Research Centre. Ridge waveguide coupler transitions the ... Per saperne di più
RFID tags are ever increasing in their daily use, from the monitoring of components, the tracking of produce during processing & production, as well as being used in much of the touch-less technologies seen today. With this technology, there has been the ever increasing need to ... Per saperne di più
INTRODUCTION. In a magnetic resonance imaging (MRI) system (see Fig. 1), it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires coupling between the nuclei and a source of radio frequency (RF) power (the transmitter). To receive a ... Per saperne di più
Simplistic, 1D analytical calculations in electro-magneto-hydrodynamics are attractive to technologists and researchers given the computational resources and time required by 3 dimensional F.E. (Finite Element) tools. However, such analytical calculations need to be checked against 3D ... Per saperne di più
Microwave impedance microscopy (MIM) is a novel mode of atomic force microscopy that can measure topography and local electrical impedance simultaneously and with nanometer spatial resolution [1]. This technique is typically used qualitatively, identifying defects in nanodevices or ... Per saperne di più
The remarkable power scaling of high power fiber lasers over the past years has become more and more challenging, because the effects of transverse mode instability (TMI) and photodarkening (PD) of the fiber are limiting the effective output power of typical industrial fiber lasers. The ... Per saperne di più
Accurate thermo-physical properties of materials are valuable for both scientific research and industrial applications. For high temperature liquid materials, two issues exclude traditional methods: elevated reactivity of test material and experimental apparatus, uncontrolled heat ... Per saperne di più
Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... Per saperne di più
