A modeling approach based on domain partitioning and use of the electromagnetic circuit formulation for full wave electromagnetic field is applied for high frequency integrated passive components, including MEMS switches. The procedure is completed by model order reduction and generation of a small compact model that describes with high accuracy the input-output behavior of the device. The main benefit...
In this study, parallel particle swarm optimization algorithm has been investigated as regards the impact of the problem properties on the execution time. Two major factors affect the performance of parallel evolutionary algorithms: the population size and the problem dimension. In this study, five well-know benchmark functions have been applied with different dimensions. Then, these functions have...
In this study, a method for solution of the multi-objective optimization problems via the desirability function aided particle swarm optimization has been proposed. The desirability function has been applied for normalization of each objective and then aggregation to a single objective. The geometric mean of the desirability values regarding each objective has been calculated as a part of the method...
Intelligent-particle swarm optimization algorithm (IPSO) is an improved heuristic method estimating the quadratic model of the problem in the hand. The conventional way to find the coefficients of the second order equation is to solve the nonhomogeneous linear equation (Ax = b), where A is the Vandermonde matrix. Although this method seems to be quite simple to execute, matrix inversion must be performed...
A new, efficient, accurate and stable method for multi-scale electromagnetic modelling of high frequency integrated circuits is proposed. The method is based on the decomposition of the domain in several-subdomains with different field regimes, and use of magnetic circuits for the global modelling of inductive effects.
This paper proposes an accurate and robust parallel algorithm for the extraction of reduced order electromagnetic models for passive components, by taking into consideration high frequency field effects. It aims at an extraction time as low as possible while keeping the accuracy control of the extracted model. The core of the reduction procedure is based on vector fitting (VF) rational approximation...
This paper investigates two methods of exploiting parallel architectures in order to efficiently extract reduced-order models for passive high-frequency integrated devices. Due to the high frequencies involved, all the effects of electromagnetic fields must be taken into account, but this leads to very large models which have to be reduced. We use an efficient technique, based on Vector Fitting, to...
In this paper, a modeling approach appropriate for the homogeneous sub-domains in integrated circuits is proposed. This modeling approach can be applied if an exponential decay of the field variation can be assumed as it happens in the substrate and in the air above the chip. The main idea is to perform a hierarchical modeling based on an exponential partitioning scheme of the homogeneous layer, conducing...
