Abstract: An energy selective antenna (ESA) concept is proposed by controlling the surface current distribution with PIN diodes. Realized gain of the proposed antenna depends on the intensity of the ...
Abstract: In this work, a reflective polarization conversion metasurface (PCM) with symmetrical L-shaped patches is proposed which enables to switch between different polarization modes by PIN diodes, ...
A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...
