Journal ArticleDOI
Versatile Manufacturing of Split-Block Microwave Devices Using Rapid Prototyping and Electroplating
TL;DR: In this article, a novel method of rapid prototyping waveguide and antenna using plating on plastic technique is presented. The part is created by high-precision three-dimensional printing and plated with copper using both electroless plating and electroplating.
Journal ArticleDOI
UWB meshed solar monopole antenna
TL;DR: In this paper, a novel combination of a parametrically optimized UWB meshed circular disc monopole antenna with a polycrystalline silicon (poly-Si) solar cell is presented and discussed.
Journal ArticleDOI
An apparatus to control and monitor the para-D2 concentration in a solid deuterium, superthermal source of ultra-cold neutrons
TL;DR: In this article, an experimental technique to convert para-to ortho-deuterium molecules by flowing D 2 gas through a cryogenic cell filled with paramagnetic hydrous ferric oxide granules was implemented, which reduced the para-D 2 concentration from 33.3% to 1.5%.
Journal ArticleDOI

TL;DR: The correlation was very accurate in patients with single radiologic nodules, however, half of the patients with more nodules showed discrepancies, and the two independent predictors of discordance between computed tomography and the number of pathologic metastases were the bilateral involvement and thenumber of radiologic nods.
Journal ArticleDOI
Symphotic Multiplexing Medium at Microwave Frequencies
TL;DR: In this paper, a volumetric metamaterial designed using the symphotic method is presented, which can realize highly efficient multiplexing structures in the strong scattering limit.
