High energy extraction of electron beam pumped KrF lasers at multi atmospheres [PDF]
, 1984 The construction is described of a simple and compact KrF laser with electron beam excitation. The electron beam is generated in a coaxial vacuum diode, driven directly by a ten-stage coaxial Marx generator.

Improvement of Pulse Shape by Reducing Ripple Using Coaxial Cable
Journal of Engineering Technology and Applied Physics, 2023 Even though pulse shape in rectangular form is desirable for most applications, pulse generated from coaxial cable has ripple and is not in desired rectangular shape. This study is to improve the pulse shape generated from coaxial cable to be rectangular

Plasmon Dispersion in Coaxial Waveguides from Single-Cavity Optical Transmission Measurements [PDF]
, 2009 We determine the plasmon dispersion relation in coaxial waveguides composed of a circular channel separating a metallic core and cladding. Optical transmission measurements are performed on isolated coaxial nanoapertures fabricated on a Ag film using ...

Negative refractive index in coaxial plasmon waveguides [PDF]
, 2010 We theoretically show that coaxial waveguides composed of a metallic core, surrounded by a dielectric cylinder and clad by a metal outer layer exhibit negative refractive index modes over a broad spectral range in the visible. For narrow dielectric gaps (

Process‐Informed Analysis of As‐Built Metal Additive Surface Features
Advanced Engineering Materials, EarlyView.This article introduces a novel method for feature‐based surface texture characterisation directly incorporating manufacturing variables into the feature extraction workflow. This marks a major step towards identifying process‐specific surface properties and their influence on part function and hence a holistic understanding of process–structure ...
