Polarization controlled directional propagation of Bloch Surface Wave

Hans Peter Herzig, Myun Sik Kim, Maria-Pilar Bernal

Bloch surface waves (BSWs) are recently developing alternative to surface plasmon polaritons (SPPs). Due to dramatically enhanced propagation distance and strong field confinement these surface states can be successfully used in on-chip all-optical integra ...

Efficient continuous-wave nonlinear frequency conversion in high-Q gallium nitride photonic crystal cavities on silicon

Nicolas Grandjean, Romuald Houdré, Jean-François Carlin, Vincenzo Savona, Matteo Galli, Momchil Minkov, Mohamed Sabry Abdel-Aliem Mohamed

We report on nonlinear frequency conversion from the telecom range via second harmonic generation (SHG) and third harmonic generation (THG) in suspended gallium nitride slab photonic crystal (PhC) cavities on silicon, under continuous-wave resonant excitat ...

Understanding and suppressing the near scrape-off layer heat flux feature in inboard-limited plasmas in TCV

Ivo Furno, Paolo Ricci, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Richard Pitts, Jan Horacek, Federico Nespoli, Federico David Halpern, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Roberto Maurizio

In inboard-limited plasmas, the scrape-off layer (SOL) shows two regions: the near SOL, extending a few mm from the last closed flux surface (LCFS), characterized by a steep gradient of the parallel heat flux radial profile, and a far SOL, typically some c ...

Understanding and suppressing the near Scrape-Oﬀ Layer heat flux feature in inboard-limited plasmas in TCV

Ivo Furno, Paolo Ricci, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Jan Horacek, Federico Nespoli, Cedric Kar-Wai Tsui, Roberto Maurizio

In inboard-limited plasmas, the Scrape-Oﬀ Layer (SOL) shows two regions: the near SOL, extending a few mm from the Last Closed Flux Surface (LCFS), characterized by a steep gradient of the parallel heat ﬂux radial proﬁle, and a far SOL, typically some cm w ...

Effect of pool confinement on pressures around a block impacted by plunging aerated jets

Anton Schleiss, Rafael Xavier Meriade Duarte

The erosion caused by jets issued from hydraulic structures progressively develops a confined scour-hole on the riverbed. A realistic scour assessment must consider both the influence of the air entrained when the jet plunges into the pool and the flow pat ...

Pull-out behavior of CFRP ground anchors with two-strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Pull-out experiments were performed on three carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in different rock types which provided different confinement levels. The CFRP tendons comprised, on the ground side, a prefabri ...

Computational challenges in magnetic-confinement fusion physics

Olivier Sauter, Ambrogio Fasoli, Jonathan Graves, Laurent Villard, Wilfred Anthony Cooper, Paolo Ricci, Stephan Brunner

Magnetic-fusion plasmas are complex self-organized systems with an extremely wide range of spatial and temporal scales, from the electron-orbit scales (similar to 10(-11) s, similar to 10(-5) m) to the diffusion time of electrical current through the plasm ...

Resonance between heat-carrying electrons and Langmuir waves in inertial confinement fusion plasmas

Stephan Brunner

In ignition scale hot plasmas, temperature gradients and thermal transport modify electron distributions in a velocity range resonant with Langmuir waves typical of those produced by stimulated Raman scattering. We examine the resultant changes to the Land ...

Lower hybrid current drive experiments with different launched wave frequencies in the EAST tokamak

Jian Wang, Joan Decker, Mingkui Wang, Fang Liu, Yong Yang

EAST has been equipped with two high power lower hybrid current drive (LHCD) systems with operating frequencies of 2.45 GHz and 4.6 GHz. Comparative LHCD experiments with the two different frequencies were performed in the same conditions of plasma for the ...
