Multiple phase derivative estimation using autoregressive modeling in holographic interferometry

Pramod Rastogi, Rishikesh Dilip Kulkarni

A novel technique is proposed for the direct and simultaneous estimation of multiple phase derivatives from a deformation modulated carrier fringe pattern in a multi-wave holographic interferometry set-up. The fringe intensity is represented as a spatially ...

Intense, carrier frequency and bandwidth tunable quasi single-cycle pulses from an organic emitter covering the Terahertz frequency gap

Christoph Peter Hauri

In Terahertz (THz) science, one of the long-standing challenges has been the formation of spectrally dense, single-cycle pulses with tunable duration and spectrum across the frequency range of 0.1–15 THz (THz gap). This frequency band, lying between the el ...

CSMA/CA in Time and Frequency Domains

Patrick Thiran, Julien Pierre Sacha Herzen

It has recently been shown that flexible channelization, whereby wireless stations adapt their spectrum bands on a per-frame basis, is feasible in practice. In this paper, we propose TF-CSMA/CA, an algorithm for flexible channelization that schedules packe ...

Direct phase derivative estimation using difference equation modeling in holographic interferometry

Pramod Rastogi, Rishikesh Dilip Kulkarni

A new method is proposed for the direct phase derivative estimation from a single spatial frequency modulated carrier fringe pattern in holographic interferometry. The fringe intensity in a given row/column is modeled as a difference equation of intensity ...

Sinusoidally Modulated Graphene Leaky-Wave Antenna for Electronic Beamscanning at THz

Julien Perruisseau-Carrier, Marc Esquius Morote

This paper proposes the concept, analysis and design of a sinusoidally modulated graphene leaky-wave antenna with beam scanning capabilities at a fixed frequency. The antenna operates at terahertz frequencies and is composed of a graphene sheet transferred ...

Remotely-Powered Batteryless Implantable Local Temperature Monitoring System for Freely Moving Mice

Mehrdad Azizighannad

Brown adipose fat tissue of a mouse dissipates the animal’s energy in the form of heat. Chronically recording the temperature of this tissue helps biologists to study the metabolism of the animal and gain new insights about the obesity in humans. Such temp ...
