Entire domain basis function expansion of the differential surface admittance for efficient broadband characterization of lossy interconnects [PDF]

, 2020
This article presents a full-wave method to characterize lossy conductors in an interconnect setting. To this end, a novel and accurate differential surface admittance operator for cuboids based on entire domain basis functions is formulated.

Design of high gradient, high repetition rate damped C-band rf structures [PDF]

, 2017
The gamma beam system of the European Extreme Light Infrastructure–Nuclear Physics project foresees the use of a multibunch train colliding with a high intensity recirculated laser pulse. The linac energy booster is composed of 12 traveling wave C-band

WSPEC: A waveguide filter-bank focal plane array spectrometer for millimeter wave astronomy and cosmology [PDF]

, 2015
Imaging and spectroscopy at (sub-)millimeter wavelengths are key frontiers in astronomy and cosmology. Large area spectral surveys with moderate spectral resolution (R=50-200) will be used to characterize large scale structure and star formation through ...

Similarity Measure of Hesitant Fuzzy Sets Based on Implication Function and Clustering Analysis

IEEE Access, 2020
Hesitant fuzzy set (HFS) permits several possible values as the membership degree of an element to a set to express the decision makers' hesitance. Since its appearance, HFS has been extensively applied in multi-attribute decision making, group decision ...

Development of a composite model derived from cardiopulmonary exercise tests to predict mortality risk in patients with mild-to-moderate heart failure [PDF]

, 2014
Objective: Cardiopulmonary exercise testing (CPET) is used to predict outcome in patients with mild-to-moderate heart failure (HF). Single CPET-derived variables are often used, but we wanted to see if a composite score achieved better predictive power ...

Periyodik yapıların ansoft HFSS kullanarak analizi

, 2021
Geniş bant düşük profil antenlerin kazanç ve bant genişliği, antenler klasik platformların iletken yüzeylerine yerleştirildiğinde ciddi olarak bozulmaya uğrar. Bu bozulma öncelikle iletken yüzeyden yansıyan faz dışı yansımalar ile antenin kendi radyasyonunun girişiminden kaynaklanmaktadır.Daha fazla açıklama gerekirse Anten ve platform arasına ...

Modeling the electromagnetic properties of the SCUBA-2 detectors

, 2004
SCUBA-2 is the next-generation replacement for SCUBA (Sub-millimetre Common User Bolometer Array) on the James Clerk Maxwell Telescope. Operating at 450 and 850 microns, SCUBA-2 fills the focal plane of the telescope with fully-sampled, monolithic ...

Magneto-Electric Dipole Antenna Arrays [PDF]

, 2014
A planar magneto-electric (ME) dipole antenna array is proposed and demonstrated by both full-wave analysis and experiments. The proposed structure leverages the infinite wavelength propagation characteristic of composite right/left-handed (CRLH ...

Effect of restrictions on television food advertising to children on exposure to advertisements for 'less healthy' foods: repeat cross-sectional study.

PLoS ONE, 2012
BackgroundIn 2007, new scheduling restrictions on television food advertising to children in the UK were announced. The aim of the restrictions was to "reduce significantly the exposure of children under 16 to high fat, salt or sugar (HFSS) advertising".
