We present the transmission characteristics of THz waves in the metal-clad antiresonant reflecting hollow waveguides. We have derived the equation for the blueshift of the resonance frequency. The effects of the waveguide structure on the blueshift of the resonance frequency are studied comprehensively. In particular, we find that the blueshift of the resonance frequency is strongly affected by...
Certain copper alloys have proved to be suitable for laser cladding onto aluminium base. By using the blown powder technique with a 1.5 KW C02 laser, clads without cracks or porosity have been produced. The base material has the composition Al Si7 Mg0.3 and the clads are made from alloyed copper with varying contents of Ni, Fe, Si and Al. Aluminium dilution in the clad can be kept lower than 1 ...
In this article, we considered the field analysis in photonic crystal Bragg fibers. We apply the method of transmission matrix to calculater the dispersion curves, the longitudinal wave number over wave number versus incident wavelength, and the field distributions of TE and TM modes in the Bragg fiber. Our analysis shows that the field of guided modes is confined in the core and can exist onl...
PurposeSurvival after lung transplantation (LTx) still remains limited by chronic allograft dysfunction (CLAD). Prior studies showed an association between graft cellular expression of the checkpoint HLA-G and acceptance, whereas conversely, soluble (sHLA-G) in plasma/BAL was associated with acute rejection. We investigated whether plasma levels extra-vesicular (EVs)-bound could predict CLAD.Me...
