Numerical Optimization of a Waveguide Transition Using Finite Element Beam Propagation
نویسندگان
چکیده
We consider a waveguide with principal guiding direction for which the beam propagation method is applicable. A simulation method based on a finite element method for Maxwell’s equation with 3D Nedelec elements is developed. The power loss of the waveguide is minimised by varying a finite number of shape parameters. We validate the method by comparing our findings to some published results.

Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis
Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

Abstract-In this work, cut-off frequencies of propagation of electromagnetic waves in a hexagonal waveguide are calculated using twodimensional (2-D) finite element method. The numerical approach is a standard one and involves six finite elements. A new type of hexagonal waveguide structure for the simple homogeneous dielectric case has been considered.
