We proposed a switchable metasurface quarter-wave plate and half-wave plate with high transmittance efficiency and polarization conversion rate over 99.9% by engineering the phase change materials ...

As the number of particles in a physical system increases, its properties can change and different phase transitions (i.e., ...

Abstract: Existing firing schemes for the firing of three-phase SCR bridge rectifiers used for industrial applications employ equidistant firing pulses. Mostly they consist of six identical phase ...
