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. >
17 &mgr;m pixel 640 x 480 microbolometer FPA development at BAE Systems
BAE Systems has developed an advanced 640 x 480 focal plane array (FPA) with a 17 &mgr;m pixel pitch. Sensitivity of ≤ 50 mK was demonstrated and the FPAs were used in imaging demonstrations. Successful scaling of BAE Systems' patented single contact per pixel, single-level microbolometer process to 17 &mgr;m pitch provides a path toward next generation microbolometer imaging systems.
