Finding resonant frequencies for high loss dielectrics in cylindrical cavities

High Eecient Parallel Computation of Resonant Frequencies of Waveguide Loaded Cavities on Jiajia Software Dsms 1

A new approach of parallel implementation of FDTD method on a novel software DSM (Distributed Shared Memory) system is proposed and implemented in this paper. Computation of the resonant frequency of a waveguide loaded cavity demonstrates the eeectiveness of the implementation. Two unique advantages of our approach are:(1) it is easy to parallelize sequential FDTD codes, (2) it is possible to r...

Unbalanced Cylindrical Magnetron for Accelerating Cavities Coating

Geometry-invariant resonant cavities.

Resonant cavities are one of the basic building blocks in various disciplines of science and technology, with numerous applications ranging from abstract theoretical modelling to everyday life devices. The eigenfrequencies of conventional cavities are a function of their geometry, and, thus, the size and shape of a resonant cavity is selected to operate at a specific frequency. Here we demonstr...

Asymmetric Resonant Optical Cavities

A new and useful type of optical resonator has been proposed based on the principles of chaos [1]. The asymmetric resonant cavity (ARC) is an extension of the concept of spherical or cylindrical dielectric resonators which have high-Q ”whispering gallery” (WG) modes trapped by total internal reflection [2]. In the ARC such a cylinder or sphere is deformed substantially but in a smooth and conve...

Numerical Study of Entropy Generation for Natural Convection in Cylindrical Cavities

In this paper, an enhanced computational code was developed using finite-volume method for solving the incompressible natural convection flow within the cylindrical cavities. Grids were generated by an easy method with a view to computer program providing. An explicit integration algorithm was applied to find the steady state condition. Also instead of the conventional algorithms of SIMPLE, SIM...
