Direct drive wind turbine generators are gaining importance for light weight, compact design in wind power generation. A new design approach of superconducting wind generator having both axial and radial air gaps between stator and superconducting rotor winding is selected for this simulation work. This paper deals with the simulation of magnetic flux distribution in stator and rotor coil of th...

As Digital Microfluidic Biochips (DMFBs) become more and more popular, largescale integration of DMFB microarrays is desirable. Multiple DMFBs with different electrode size from various manufacturers may need to be integrated into a single chip. However, the incompatibility of electrode size poses a problem for the integration of multiple DMFBs. In this paper, a droplet size adapter to convert ...

This paper describes the Virtual Prototype of a Dielectric Window (DW) for High Power Microwave Vacuum Tubes and Linear Accelerators (LINAC). Design formulas are provided and Computer Aided Design techniques based on COMSOL Multiphysics are proposed. The virtual prototype considers the Thermo-mechanical effects due to the joule effect induced by the power which crosses the DW and the Thermal co...

As energy can neither be created nor be destroyed but can be transformed from one form to other form, depending on application. In some cases energy released/ absorbed in any reaction sometimes will alter the process parameters and cause disturbance in normal flow of operation. This effect has its impact even in fundamental wave propagation properties and results in introduction of unwanted noi...

This paper outlines the results of finite element analyses to study the radiation pattern of an implanted medical device. Also presented are simulation results used to design an electrically small antenna for a portable control unit that communicates with the implants over a 416 MHz to 453 MHz data link. Alfred Mann Foundation's Functional Electrical Battery Powered Micro-Stimulator system (FEB...
