Patch antennas on inhomogeneous substrates

Patch antennas on inhomogeneous substrates are analyzed with the stable FEM-FDTD hybrid method [T. Rylander and A. Bondeson, “Stable FEMFDTD hybrid method for Maxwell’s equations,” Comput. Phys. Comm. 125, 75 (2000)] and an analytic propagator technique. For inhomogeneous substrates with a fixed homogenized value of the permittivity, our results conjecture that a decrease of the permittivity in the

Parameter Optimization of a Paper Machine Model

In this paper, the problem of calibrating a paper machine dryer section model to measurement data is treated. The model, which is dynamic, nonlinear and of large scale, is implemented in Modelica and Dymola. The purpose of the model is to evaluate, in simulation, new control structures before application to the plant. This approach requires a well calibrated model in order for simulation results t

Generation of Minimal Leakage Input Vectors with Constrained NBTI Degradation

Technology scaling has caused Negative Bias Temperature Instability (NBTI) to emerge as a major circuit reliability concern. Simultaneously leakage power is becoming a greater fraction of the total power dissipated by logic circuits. As both NBTI and leakage power are highly dependent on vectors applied at the circuit’s inputs, they can be minimized by applying carefully chosen input vectors durin
