Most ionic crystals have strong reflection bands in the far infrared. Many such crystals are also transmissive to infrared radiation. An unstable resonator that exploits these properties is described. Preliminary results from a device 134 cm long and of 6 ...
A numerical holographic method, which is able to determine the amplitude components of the Jones vector of a wavefront in addition to its phase and amplitude, is presented. Two reference waves, with orthogonal polarisations interfere with the transmitted o ...
At frequencies below the electron cyclotron and above the lower hybrid frequency in a magnetoplasma, the refractive index is anisotropic and shows resonances at certain angles caused by electron inertia. For a radiating antenna in a plasma, the short wavel ...
Shore protection in confined water bodies is of major importance in Switzerland where many lakes suffer severe shore erosion. It occurs mainly in shallow zones due to several reasons such as: the fluctuations of the water level , the wind-wave impact durin ...
This paper presents a microfabricated impedance spectroscopy flow cytometer which permits rapid and easy dielectric characterization of cells as they flow in a microchannel. Both a simple theoretical model and a finite element simulation show that the effe ...
The action of water waves moving over a porous seabed drives a seepage flux into and out of the marine sediments. The volume of fluid exchange per wave cycle may affect the rate of contaminant transport in the sediments. In this paper, the dynamic response ...
We present measurements of decay amplitudes and triple-product correlations in B→K* decays based on 253fb-1 of data recorded at the Υ(4S) resonance with the Belle detector at the KEKB e+e- storage ring. The decay amplitudes for the three different helicity ...
