Analysis and Implementation of A LLC Resonant Converter for Magnetron Modulator

Multifunctional Spaceplates for Optical Aberration Correction

“…Over the last two decades, extensive research has been devoted to the development of nano-optical imaging systems with reduced size and weight . A major focus has been at the device level, where optical metasurfaces have been developed that seek to substitute traditional bulky optics with nanostructured thin films. − Metasurfaces can be designed to exhibit a broad range of amplitude and phase responses, leading to gratings, lenses, and holographic surfaces featuring new regimes of spectral − and polarization control. − A more recent development has been the reduction of the separation distances between optical components using spaceplates (Figure a), which are volumetric nonlocal optical devices that can emulate the optical responses of free space within a reduced physical space. − Concepts such as the spaceplate are ultimately required to enable reductions in total optical system size while retaining image fidelity and spectral range.…”

A High Frequency Converter for EV Application

“…In this paper presented a, a high performance DC-DC converter isproposed to significantly reduce the current ripple of fuelcell, minimized the size and the weight, increase theefficiency and the lifetime of the fuel cell [3].However this configuration required many fuel cells, whatincreases the cost of the system. Conventional converter describes it allows eliminating the rippleof the low-frequency current to feed a single load [4]. Conventionalpropose a multi-level DC-DC converter which feeds a residence with electricalenergy through a fuel cell [5].…”
