Low temperature co-fired ceramic (LTCC) with silver and gold conductor systems offer a low cost, high performance, and high reliability solution utilizing the advantages of ceramic technology. Gold conductors are generally used in applications requiring best reliability in harsh environmental conditions. Gold conductors are bonded to active or passive components through wirebonding, soldering, ...

Subconductor methods or partial wire methods yield reliable results for conductor parameters such as inductance, capacitance, conductance and resistance and can be used to estimate these parameters for conductor configurations involving complex geometries which cannot be handled using analytical methods. The values of inductances obtained using partial wire method are critically compared with v...

A novel wearable button antenna sensor is proposed for the concept of simultaneous wireless information and power transfer (SWIPT). This integrates two working modes information, respectively, optimizes efficiency. An omni-directional radiation pattern achieved in 3.5 GHz World Interoperability Microwave Access (WiMAX) band to support on-body communications, while a circularly polarized broadsi...

Microcantilevers are key components of many Micro-Electro-Mechanical Systems (MEMS) and Micro-Optical-ElectroMechanical Systems (MOEMS) because slight changes to them physically or chemically lead to changes in mechanical characteristics. An inexpensive dual-fiberoptic microcantilever proximity sensor and model to predict its performance are reported here. Motion of a magnetic-material-coated c...

wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

High-resolution magnetotelluric (MT) studies of the San Andreas fault (SAF) near Hollister, CA have imaged a zone of high fluid content flanking the San Andreas fault and extending to midcrustal depths. This zone, extending northeastward to the Calaveras fault, is imaged as several focused regions of high conductivity, believed to be the expression of tectonically bound fluid pockets separated ...

This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...

Abstract Helix-fiber composites (HFCs), which involve wrapping a material around flexible core, are of interest for intelligent stretchable functional materials or devices. Here, we reveal that mechanical coupling between the core and plays critical role in controlling structure properties. Our results show properties HFC can be programmed by precisely tuning strength among them. Interestingly,...
