Rigorous evaluation of propagation losses in arbitrarily shaped waveguide structures using boundary integral – resonant mode expansion and perturbation of boundary conditions

Michael Mattes

The accurate consideration of propagation losses in arbitrarily shaped waveguide-based structures is studied in this paper. For such a purpose, a software tool based on the perturbation of the boundary conditions on the waveguide metallic walls and on the ...

Manipulating Bloch surface waves in 2D: a platform concept-based flat lens

Hans Peter Herzig, Elsie Barakat, Libo Yu, Tristan Sfez, Lubos Hvozdara, Joab Di Francesco

At the end of the 1970s, it was confirmed that dielectric multilayers can sustain Bloch surface waves (BSWs). However, BSWs were not widely studied until more recently. Taking advantage of their high-quality factor, sensing applications have focused on BSW ...

Wideband generation of pulses in dual-pump optical parametric amplifier: theory and experiment

Camille Sophie Brès, Mohammad Amin Shoaie, Amirhossein Mohajerin Ariaei

The generation of pulses in dual-pump fiber optical parametric amplifier is investigated. Theoretically, it is shown that in an analogical manner to pulse generation in single-pump fiber optical parametric amplifiers, the generated pulse shape depends on t ...

A Multipath Sparse Beamfroming Method

Hervé Bourlard, Volkan Cevher, Afsaneh Asaei

A novel formulation of beamforming is proposed for acquisition of the signals in reverberant acoustic clutter of interferences and noise. We derive the beamforming methods which incorporate the sparsity structure pertained to the acoustic source distributi ...

On the Validity of Approximate Formulas for the Evaluation of the Lightning Electromagnetic Fields in the Presence of a Lossy Ground

The accuracy of approximate formulas for the evaluation of lightning electromagnetic fields above and inside a lossy ground is investigated taking as reference full-wave numerical results obtained using a parallel implementation of the finite-difference ti ...

Modulations of Spin Echoes in Liquids

Geoffrey Bodenhausen

Echo modulations that arise in Carr–Purcell–Meiboom–Gill (CPMG) spin echo sequences and stem from homonuclear couplings can be suppressed by different methods. The evolution under homonuclear couplings can be either ‘‘locked’’ or ‘‘refocused’’, leading to ...

A novel low complexity data demodulation algorithm for pulse position modulation

Pierre-André Farine, Cyril Botteron

In this paper, a low complexity data demodulation algorithm is proposed that requires time of arrival information of the received signal exclusively. As an application example, the algorithm is applied to an ultra-wideband impulse radio communication syste ...

Approximate Ergodic Capacity of a Class of Fading 2x2x2 Networks

Michael Christoph Gastpar, Chien-Yi Wang

We study a 2-user 2-hop network with 2 relays in which channel coefficients are independently drawn from continuous distributions and vary over time. For a broad class of channel distributions, we characterize the ergodic sum capacity within a constant num ...
