Ray Optics Analysis Explanation of Beam-Splitting Condition in Fabry-Pérot Antennas
IEEE Access, 2018 This paper presents a theoretical analysis where general and accurate formulas for the design of Fabry-Pérot antennas (FPA) are derived from a simple ray optics approach.

Finite Volume Effects and Quenched Chiral Logarithms [PDF]
, 1996 We have measured the valence pion mass and the valence chiral condensate on lattice configurations generated with and without dynamical fermions. We find that our data and that of others is well represented by a linear relationship between $m_{\pi}^2 ...

Reentrant valence transition in EuO at high pressures: beyond the bond-valence model
, 2012 The pressure-dependent relation between Eu valence and lattice structure in model compound EuO is studied with synchrotron-based x-ray spectroscopic and diffraction techniques.

Masses and decay constants of pions and kaons in mixed-action staggered chiral perturbation theory
, 2017 Lattice QCD calculations with different staggered valence and sea quarks can be used to improve determinations of quark masses, Gasser-Leutwyler couplings, and other parameters relevant to phenomenology.

Valence Instability and Superconductivity in Heavy Fermion Systems
, 2006 Many cerium-based heavy fermion (HF) compounds have pressure-temperature phase diagrams in which a superconducting region extends far from a magnetic quantum critical point.

Accurate Positioning System Based on Chipless Technology
Sensors, 2019 In this paper, we present an accurate method to localize an object on a 2D plan using the chipless technology. This method requires a single antenna and a chipless tag.
