UV-patternable polymers with selective spectral response

Jürgen Brugger, Victor Javier Cadarso Busto

We present the characterization of dyed doped/modified Epocore resist (Microresist Technology, Germany) with three commercially-available dyes (Proquimac Color, Spain). After being doped with lilac, red and yellow dyes in a 1:2500 ratio (dye:Epocore, w:w), ...

Efficient Discriminative Projections for Compact Binary Descriptors

Vincent Lepetit, Tomasz Piotr Trzcinski

Binary descriptors of image patches are increasingly pop- ular given that they require less storage and enable faster processing. This, however, comes at a price of lower recognition performances. To boost these performances, we project the image patches t ...

Electromechanically induced absorption in a circuit nano-electromechanical system

Tobias Kippenberg, Xiaoqing Zhou, Albert Schliesser

A detailed analysis of electromechanically induced absorption (EMIA) in a circuit nano-electromechanical hybrid system consisting of a superconducting microwave resonator coupled to a nanomechanical beam is presented. By performing two-tone spectroscopy ex ...

A 2.4 GHz MEMS based sub-sampling receiver front-end with low power channel selection filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling RF front end which exploits the intrinsically high quality factor of MEMS devices for performing channel filtering directly at RF is proposed in this work. This narrow band filtering at RF also acts as a good anti-aliasing filter to support ...

Pulse distortion in linear slow light systems: theoretical limits and compensation strategies

Luc Thévenaz

We study analytically pulse distortion in linear slow light systems, and provide some useful limits on these devices. Additionally, we also show that the contributions of phase and amplitude broadening can be de-coupled and quantified. It is observed that ...

Evaluating two model-free data interpretation methods for measurements that are influenced by temperature

Ian Smith, Ngoc Thanh Trinh, Irwanda Laory

Interpreting measurement data to extract meaningful information for damage detection is a challenge for continuous monitoring of structures. This paper presents an evaluation of two model-free data interpretation methods: moving principal component analysi ...

Fully Passivated AlInN/GaN HEMTs With f(T)/f(MAX) of 205/220 GHz

Nicolas Grandjean, Jean-François Carlin

We report the fabrication and characterization of 30-nm-gate fully passivated AlInN/GaN high-electron mobility transistors (HEMTs) with cutoff frequencies f(T) and f(MAX) simultaneously exceeding 200 GHz at a given bias point. The current gain cutoff frequ ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter

Seyed Armin Tajalli, Yusuf Leblebici

A sixth-order low-pass

g_m

-C filter with a very wide tuning range (

f_c

= 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...

Designing Practical Filters For Sound Field Reconstruction

Martin Vetterli, Mihailo Kolundzija, Christof Faller

Multichannel sound field reproduction techniques, such as Wave Field Synthesis (WFS) and Sound Field Reconstruction (SFR), define loudspeaker filters in the frequency domain. However, in order to use these techniques in practical systems, one needs to conv ...

UMTS-WiFi Switchable Bandpass Filter

Julien Perruisseau-Carrier

In this paper a reconfigurable bandpass filter able to switch between WiFi and UMTS transmit band standards is presented. The filter is designed in such a way that center frequency and bandwidth specifications are precisely met by defining a switchable fil ...
