High Performance, Continuously Tunable Microwave Filters Using MEMS Devices With Very Large, Controlled, Out-of-Plane Actuation

Software defined radios (SDR) in the microwave X- and K-bands offer the promise of low cost, programmable operation with real-time frequency agility. However, the real world in which such radios operate requires them to be able to detect nanowatt signals i ...

Area and Power Efficient Ultra-Wideband Transmitter Based on Active Inductor

Catherine Dehollain, Kerim Türe, Arnout Jan J Devos, Franco Maloberti

This paper presents the design of an impulse radio ultra-wideband (IR-UWB) transmitter for low-power, short-range, and high-data rate applications such as high density neural recording interfaces. The IR-UWB transmitter pulses are generated by modulating t ...

Signal processing apparatus and method for transmitting and receiving coherent parallel optical signals

Tobias Kippenberg

A signal processing apparatus, being configured for transmitting and receiving coherent parallel optical signals, comprises a transmitter apparatus including a first single soliton micro-resonator device and a modulator device, wherein the first single sol ...

Optically isolated millimeter-wave detector for the Toroidal Plasma Experiment

Timothy Goodman, Stefano Alberti, Anja Skrivervik, Ivo Furno, Marcelo Baquero Ruiz, Gennady Plyushchev, Oulfa Chellaï, Fabian Manke

We have designed and built an optically isolated millimeter-wave detection system to prevent interference from a nearby, powerful, 2.45 GHz microwave source in millimeter-wave propagation experiments in the TORoroidal Plasma EXperiment (TORPEX). A series o ...

3D printed microwave cavity for atomic clock applications: proof of concept

Anja Skrivervik, Emile Jacques de Rijk

The authors present the realisation and characterisation of an additively manufactured (AM) microwave resonator cavity for double-resonance (DR) vapour-cell atomic clocks. The design of the compact microwave cavity is based on the loop-gap resonator approa ...

Grouping and “objecthood” effects in the Ebbinghaus illusion

Michael Herzog, Aline Françoise Cretenoud, Einat Rashal

We examined the effect of grouping processes on the Ebbinghaus illusion by manipulating objecthood: the degree to which an object is perceived as a cohesive entity. We presented observers with squares as targets and inducers and manipulated the degree of t ...

FM-UWB: Towards a Robust, Low-Power Radio for Body Area Networks

Christian Enz, John Farserotu, Vladimir Kopta

The Frequency Modulated Ultra-Wideband (FM-UWB) is known as a low-power, low-complexity modulation scheme targeting low to moderate data rates in applications such as wireless body area networks. In this paper, a thorough review of all FM-UWB receivers and ...
