Vortex lattice dynamics has been studied in thin Nb superconducting films sputtered on top of a dense triangular array of V dots with and without an intermediate SiO2 insulating layer. While the insulating layer modifies only slightly the Nb film corrugation, it reduces superconducting commensurability effects (CE) substantially. This implies that superconducting commensurability is dominated b...

This project addressed the analysis and design of a cryogenic microwave anisotropic wave guiding structure that isolates an antenna from external incident fields from specific directions. The focus of this research was to design and optimize the radome's constituent material parameters for maximizing the isolation between an interior receiver antenna and an exterior transmitter without signific...

An inline spectrometer has been developed to monitor shot-by-shot pulse energies of a two-color X-ray beam. A thin film of diamond allows inline operation with minimum absorption. The absolute pulse energy for each color is determined by the inline spectrometer combined with a total pulse-energy monitor. A negative correlation is found between the two-color pulse energies.

in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

BACKGROUND Participation and performance trends in age group athletes have been investigated in endurance and ultraendurance races in swimming, cycling, running, and triathlon, but not in long-distance inline skating. The aim of this study was to investigate trends in participation, age, and performance in the longest inline race in Europe, the Inline One-Eleven over 111 km, held between 1998 a...

In this work, 60-GHz wideband, compact vertically polarized end-fire monopole-based Yagi antenna-in-package is proposed for mobile devices. The antenna was arranged like a monopole array, and the size minimized by utilizing image effect. Advantages of structure include reduction bond-wire loss inserting cavity to make chip same height due For practical use, interconnected with CMOS via intercon...

In this article, we present and analyze the numerical stability of two coupled finite element formulations. The first one is $h$ - notation="LaTeX">$a$ -formulation well suited for modeling systems with super...
