In modern aircraft designs, there is a need for new high power isolated DC/DC converters. Full bridge derived topologies are appropriate for these specifications. Aircraft specifications are demanding and a high power density is needed. In order to decrease volume, reactive component, such as the transformer have to be optimized in volume, weight and loses. High frequency is needed to decrease inductive...
Subwavelength plasmonic nanoantennas are key elements in nanophotonics, with application prospects in multiple disciplines. Here we show that magnetic (sandwich) nanoantennas can be efficiently integrated on a silicon chip and properly fed by using the TM mode of the waveguide at telecom wavelengths.
Left ventricular noncompaction (LVNC) is a primary cardiomyopathy that can present with recurrent ventricular arrhythmias (VAs). Data on the benefit of catheter ablation of VAs in LVNC are lacking.The purpose of this study was to describe the electrophysiologic features and outcomes of catheter ablation of VAs in LVNC.The cohort consisted of 9 patients (age 42 ± 15 years) with diagnosis of LVNC based...
The cure of an epoxy resin/polyamidoamine hardener system was followed in real-time by magnetic resonance (MR) with a purpose-built portable probe that was designed with a magnet array and a radio-frequency coil geometry that maximize its sensitivity. The MR results demonstrated that the effects of cross-linking during the cure are manifest in changes in the experimental signal amplitude and decay...
We present a fishnet metamaterial design whose dimensions have been engineered to enhance a second-order magnetic resonance appearing at visible wavelengths. Both negative permittivity and permeability are achieved in this spectral range.
