Efficient non-uniform orthogonal mesh generation algorithm for cylindrical FDTD applications
The paper presents an efficient non-uniform, orthogonal mesh generation algorithm for the analysis and design of cylindrical microwave devices and integrated circuits using the cylindrical finite-difference time-domain (CFDTD) methods. By using this algorithm, we can easily generate a suitable CFDTD grid which is fitting for the developed CFDTD Maxwell's solver.
Analysis of cylindrical microstrip lines utilizing the finite difference time-domain method
This paper presents full-wave analysis of the cylindrical striplines and the cylindrical microstrip lines utilizing the finite difference time-domain method in a circular-cylindrical coordinate system. Numerical results on the normalized characteristic impedance are in good agreement with the available results. Furthermore, the junctions of the coaxial transmission line and the cylindrical microstrip line are analyzed to show the usefulness of this method. >
Rapid determination of the effectiveness of insect resistant packaging
A technique was developed to evaluate the usefulness of odour barriers and to determine the effect of package content in consumer size packages on resistance to infestation by insects. Female Plodia interpunctella (Hubner) could distinguish sealed packets containing food from non-food items as a suitable site for oviposition. Utilization ofthis technique will reduce the time needed to evaluate new materials for use in insect resistant packaging.
