This paper describes the simulation, design, realization, and experimental test of a tapered transmission line (TL) for adapting a broad-band impulse generator to a radiating antenna, for a frequency range of 50 MHz-1 GHz. Two different taper geometries ar ...
We study charmless B+ meson decays to the p Lambda pi(+)pi(-) final state using a 605 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. There are significant signals found wit ...
We report on the microfabrication and testing of a chip- scale plasma light source. The device consists of a stack of three anodically bonded Pyrex wafers, which hermetically enclose a gas-filled cavity containing interdigitated Aluminum electrodes. When t ...
The SPS kickers are major contributors to the SPS transverse beam coupling impedance. The current ”flat chamber” impedance model for a kicker is obtained by applying form factors to the theoretical impedance of an axisymmetric ferrite beam pipe. This model ...
Upgrades of the CERN particle accelerators complex are planned to increase the potential of physics discovery in the LHC. In this respect, the beam coupling impedances of the SPS and LHC are expected to be among the limitations to the intensity upgrade sch ...
A resonant planar antenna as an inductive plasma source operating at 13.56 MHz inside a low pressure vacuum vessel is presented for potential plasma processing applications. Its principle consists in interconnecting elementary resonant meshes composed of i ...
In bioelectric recordings, an electrode-skin impedance mismatch leads to a reduced common-mode rejection ratio (CMRR) of the amplifier. For this reason, the impedance of each individual electrode-skin contact is usually measured prior to a recording. The m ...
Using B. Zotter’s formalism, we present here a novel, efficient and exact matrix method for the field matching determination of the electromagnetic field components created by an offset point charge travelling at any speed in an infinitely long circular mu ...
A very wideband slot antenna with reconfigurable stopband is presented. The reconfiguration is achieved by modifying the effective length of an embedded stopbandresonator by means of three pairs of PIN diodes. Four different operative states—three of them ...
Diffusion LMS is a distributed algorithm that allows a network of nodes to solve estimation problems in a fully distributed manner by relying solely on local interactions. The algorithm consists of two steps: a consultation step whereby each node combines ...
