Measurement and Analysis of High Frequency Resonances In Printed Circuit Boards
… higher frequencies. For example, high humidity models of PCB materials do not correlate well to actual measurements and classic models for losses associated with copper surface roughness break down around 5 gigahertz (GHz). Industry often uses the infinite pole Debye model to simulate the …

A Mossbauer study of some industrial applications of organotin compounds.
… tin moiety.Finally, in chapter six a simple Debye model of the solid has been applied to variable temperature Mossbauer data to suggest possible structures for two bis(triaikyltin)compounds containing two electronically different tin sites.

The fate of organotin biocides in marine antifouling elastomers.
… tin atom is penta-coordinate. Application of the Debye model of solids yielded a value of the recoilless fraction at 80K, f(80K), of 0.30 and the vibrational freedom of the tin atom was isotropic. This associated structure was observed to break down upon dispersion into uncured neoprene. The …

Monitoring glycation through the intrinsic fluorescence of biological fluorophores
… when decays are fitted to a 2-exponential model, however fitting to a non-Debye model more clearly highlights the impact of glucose. We also studied the intrinsic fluoresce of mouse skin and human fingernails. In an initial pilot study on mouse skin, our results suggested that collagen, …

Microwave Tomography Using Stochastic Optimization And High Performance Computing
… microwave tomography system is capable of modelling complex, heterogeneous, and dispersive media using the Debye model. A detailed explanation of the dispersive FDTD is presented herein. The system uses scattered field data due to multiple excitation angles, frequencies, and observation …

Atomic structures of carbon nanomaterials studied by coherent electron diffraction
… at ~0.2 Å. The thermal displacements follow the Debye model with a Debye temperature of 284 K, which is an important parameter for understanding the thermal properties of CNTs. Graphene can be folded to create the folded structure with mechanical and electronic properties very different from the …

Efficient Finite Element Electromagnetic Analysis for High-Frequency/High-Speed Circuits And Multiconductor Transmission Lines
… the incorporation of lumped networks and circuit models in a distributed finite element model. An adaptive multipoint model order reduction method is developed for fast broadband analysis. (2) Development of a fast and accurate multiconductor transmission line simulator and parameter extractor …
