Abstract:
Wireless power transfer devices are provided. The wireless power transfer device may include a plurality of stacked resonance structures, and adhesive layers between the resonance structures. Each of the resonance structures includes a base board including a base coil, interposer boards including interposer coils and stacked on the base board, and conductive pillars penetrating the base board and the interposer board. The conductive pillars connect the interposer boards to each other.
Abstract:
Provided are a spatial light modulator (SLM) and a method of fabricating the same. The complex spatial light modulator includes a thin film transistor (TFT) layer provided on a substrate, an amplitude type SLM and a phase type SLM electrically connected to the TFT layer, and a first polarizer provided on the phase type SLM, wherein the TFT layer includes transistors electrically connected to the amplitude type SLM and the phase type SLM, respectively, and the amplitude type SLM and the phase type SLM are commonly and electrically connected to the TFT layer and driven.
