A 2 % bandwidth C-band filter using cascaded split ring resonators

Alejandro Borja, Jorge Carbonell, Vicente Boria, Joaquin Cascon, Didier Lippens

A 2% bandpass filter with an out-of-band rejection in excess of 30 dB was demonstrated experimentally for operation in the C-band (central frequency at 4.5 GHz). Narrow bandwidth and high rejection were achieved by cascading three double split-ring resonators (SRRs) magnetically coupled to a...

Carrier multiplication in bulk and nanocrystalline semiconductors : mechanism, efficiency, and interest for solar cells

Christophe Delerue, Guy Allan, Joep J. H. Pijpers, Mischa Bonn

Carrier multiplication (CM), the possibility to generate more than one exciton in a semiconductor quantum dot (QD) after absorption of a single photon has been intensely debated in recent years. Following on previous theoretical and experimental work, we report here that: (1) although the CM factor...

Preparation of boron-doped diamond nanowires and their application for sensitive electrochemical detection of tryptophan

Sabine Szunerits, Yannick Coffinier, Elisabeth Galopin, Josef Brenner, Rabah Boukherroub

The paper reports on the fabrication and electrochemical investigation of boron-doped diamond nanowires (BDD NWs) electrodes. The nanowires were obtained directly from highly doped polycrystalline diamond substrates using reactive ion etching (RIE) with oxygen plasma. The technique does not require...

Composite left/right-handed stacked hole arrays at sub-millimeter wavelength

Shengxiang Wang, Frédéric Garet, Karine Blary, Charles Croënne, Eric Lheurette, Jean-Louis Coutaz, Didier Lippens

High-transmissivity composite left/right-handed uniaxial bulk metamaterials were fabricated in a multilayered dielectric/hole metal array technology and experimentally assessed at submillimeter wavelengths (0.4–0.9 THz) by time-domain spectroscopy. From the frequency dependence of the complex...

Paths Complex Gain Tracking Algorithms for OFDM Receiver in Slowly-Varying Channels

Laurent Ros, Hussein Hijazi, Eric Pierre Simon

This paper deals with channel estimation for Orthogonal Frequency Division Multiplexing (OFDM) systems over time-varying fading channels. In conventional methods, the least-squares (LS) estimate is obtained over the pilot subcarriers, and next interpolated over the entire frequency grid. Those...

Channel Estimation for MIMO-OFDM Systems in Fast Time-Varying Environments

Hussein Hijazi, Eric Pierre Simon, M. Lienard, Laurent Ros

A channel estimation algorithm for MIMO-OFDM systems in Fast Time-Varying Environments is proposed. The channel estimation function is based on the equivalent discrete-time channel taps or on the physical propagation channel parameters. To handle rapid variations of channels within a transmission...
