A new concept for a 1 × 2 micromechanical optical switch with 10 μs of switching speed, 29 dB of ON/OFF ratio, and insertion loss of −7.22 dB for λ = 1550 nm and −4.96 dB for λ = 635 nm is presented. The idea is to insert a micromechanical switching mechan ...
The modeling and design of metamaterial composite right/left handed transmission lines (CRLH-TL) is usually based on the assumption that its unit cell is small in terms of the host TL wavelength (d 0). However, it was also shown that this assumption is not ...
Periodic structures, such as frequency-selective surfaces (FSSs) and photonic band-gap (PBG) materials, exhibit total reflection in specific frequency bands while total transmission in other bands. They find numerous applications in a large field of the el ...
A method for the fabrication of bow-tie optical antennas at the apex of pyramidal Si3N4 atomic force microscopy tips is described. We demonstrate that these novel optical probes are capable of sub-wavelength imaging of single quantum dots at room temperatu ...
This paper presents the modeling and design of one-dimensional metamaterial phase shifters (MPSs) in monolithic-microwave integrated-circuit technology based on the composite right/left-handed transmission-line approach. From a theoretical point-of-view, w ...
Abstract—This work reports on the fabrication and characterization of the organic thin film transistors OTFTs. Pentacene transistors are fabricated in top and bottom S/D contact configurations on preoxidized Si wavers. Three different metals – Pt, Au and A ...
We present an integrated composite right/left handed transmission line (CRLH-TL) phase shifter analogically controlled by means of a MEMS series capacitor. The device is based on coplanar waveguide (CPW) technology and operates at a central frequency of 18 ...
The X-mode radial correlation reflectometry diagnostic on JET has long suffered from strong signal attenuation in the original transmission lines. To reach higher performances, new low-attenuation corrugated circular waveguides and a new cluster of six ant ...

Three different kinds of two-port flexural resonators, with both clamped and free ends, and with nominal resonance frequencies between 5 MHz and 50 MHz, were designed and fabricated. Among them, a novel free-free third-mode resonator, as well as a tunable ...
