Multilayer Ionic Transducers
… method capable of modeling the structure of the multilayer transducers is developped. It is used to model the interfacial friction in multilayer transducers. Experiments on transducers with one to three layers are performed and the results are compared to Newbury's equivalent circuit model, which …

Survivable paths in multilayer networks
We consider the problem of protection in multilayer networks. In single-layer net- works, a pair of disjoint paths can be used to provide protection for a source-destination pair. However, this approach cannot be directly applied to layered networks where disjoint paths may not always exist. In …

Multilayer composite photonic bandgap fibers
… that lead to the successful fabrication of multilayer composite photonic bandgap fibers. The pertinent background in electromagnetic theory of multilayer dielectric mirrors and optical fibers is surveyed. Materials properties constraints are outlined, with emphasis on those constraints …

Dimensional Stability of Multilayer Circuit Boards
… residual deformation and warpage in a model multilayer circuit board construction of a common composite substrate (7628 fabric style). A numerical procedure based on classical lamination theory with non-isothermal viscoelastic constitutive relations is developed to predict the deformation and …

Multilayer Techniques to Address Parameter Variation
Within-die process variation causes individual cores in a Chip Multiprocessor (CMP) to differ substantially in both static power consumed and maximum frequency supported. In this environment, ignoring variation effects when scheduling applications or when managing power with Dynamic Voltage and …

Electrical crosstalk in multilayer ceramic substrates
… in hybrid circuits. This occurs especially in multilayer thick film circuits. Crosstalk studies at high frequencies apply transverse electromagnetic (TEM) or quasi-TEM mode. However, the TEM mode theory is not applicable at low frequencies and low frequency-crosstalk is still a concern for …

Organic multilayer photoconductor utilizing a spacer layer
… concept, we fabricate and characterize lateral multilayer photoconductors composed of small molecule organic films. It is experimentally demonstrated that the utilization of a spacer layer can produce an order of magnitude enhancement in quantum efficiency over the of a spacer layer can produce …

Computer-aided design for multilayer microfluidic chips
Microfluidic chips fabricated by multilayer soft lithography are emerging as "lab-on-a-chip" systems that can automate biological experiments. As we are able to build more complex microfluidic chips with thousands of components, it becomes possible to build devices which can be programmatically …

Indentation Behavior of Multilayer Al/SiC Thin Films
… Youngs modulus, of bulk and thin film materials. Multilayer thin films are an important subset of materials in which alternating layers of two or more materials are deposited on a substrate. Fabrication of multilayer films can result in imperfect layer geometry, particularly the flatness and …

New Algorithms and Bounds for Multilayer Channel Routing
This thesis studies the multilayer channel routing problem (CRP). New algorithms are presented in which the number of layers is a parameter of the problem, and the area of the solution improves as the number of layers is increased.
