By further analysis to the ratios of the core cross-section, we have obtained an equation regarding the minimum excitation current for contracted core structure fluxgate when the ratio tends to zero.
As an example, by using this technique, effects of the trapezoid core cross-section on transmission characteristics are performed for a 33 × 33 polymer AWG multiplexer around the central wavelength of 1.550918 μm with the wavelength spacing of 0.8 nm.
The OEC decreases with square of the ratio of pick up core cross-section to that of the excitation core, while it changes little with the ratio of their lengths.
In this paper, we are presenting an analytical study of the effect of curvature of the spiral shape on the modal dispersion characteristics of the waveguide whose core cross-section is bounded by two involuted spirals of the form 1/r=ξθ, where ξ is a constant and represents the curvature of the spiral taken to design the waveguide into consideration.
Based on the perturbation theory, a technique named "equivalent rectangular waveguide method" is presented for analyzing the transmission characteristics of arrayed waveguide grating (AWG) multiplexers with trapezoid core cross-sections.
Computed results show that the trapezoid core cross-sections result in the shift of the transmission spectrum, and lead to the increase of the crosstalk compared with the device originally designed with exact rectangular core cross-sections.
Some variables, such as tilt angle, size of core cross-section and thickness of sheet shell, have been proved to be effective in controlling the collapse mode and crushing performance of STFD-HAT sections by analysis on energy absorption and RSS of result curves.
Eight fluxgate sensors with different ratio of core cross-sections and core lengths were developed and investigated.
The second part of the paper deals with the development of a fire design method for axially loaded CFT columns based on the general rules stablished in Eurocode 4 Part 1-1 and employing the concept of room temperature equivalent concrete core cross-section.
Availability of automated generation of T H feedbacks along capabilities to analyze neutronics of the core and cross sections generation, make IRTRAN capable of accurate modeling of conventional as well as advanced future reactor systems.
Modes 1 and 2 deformations are identified for the well-known quasi-inextensional, regular (asymmetric) progressive folding of thin-walled sections having a rectangular (core) cross-section, such as square and top-hat sections.
