Topology Synthesis of the Multi-Tapped Meander Delay Line using Monte Carlo Method

Abstract

The algorithm for synthesis of the multi-tapped meander delay line (MTMDL) topology is proposed in this article. The algorithm is based on search of construction parameters of the MTMDL according to Monte Carlo method. Proposed algorithm was realized as software and tested on 14 nodes computer cluster. Experimental synthesis of lines has shown adequacy of the suggested algorithm. It has been shown that increasing number of nodes in the cluster, synthesis is executing faster and parallel part of the algorithm approaches to 90 percent of total algorithm. It is revealed that the maximal efficiency of the algorithm is achieved when the number of cluster nodes reaches the number of all issued synthesis processes.

“…Tačiau skaitinių metodų taikymas leidžia įvertinti daugiau faktorių nei analitiniais metodais grįsti modeliai, pavyzdžiui, paviršinį ir galų efektus laidininkuose, nuostolius dielektrikuose ir elektrodų laikikliuose bei leidžia gauti pakankamai tikslius rezultatus (Pomarnacki, Urbanavičius 2009). Darbe (Pomarnacki et al 2012) siūloma LS analizei taikyti daugialaidžių linijų ir skaitinių metodų derinius, taikant technologijos, leidžiančias paskirstyti uždavinius tarp asmeninių kompiuterių arba naudoti grafinius ar specialios paskirties mikroprocesorius (Nvidia 2012), leidžiančius išlygiagretinti skaičiavimus.…”

Parallel Algorithms for the Synthesis of the Multi-Tapped Meander Delay Lines

“…Proposed parallel synthesis algorithm of the MTMDL, based on the SAT, differs from the algorithm based on Monte Carlo method [7] by the approach of search of construction parameters of the MTMDL.…”

“…Another way to decrease time of the analysis and the synthesis processes is use of parallel computational techniques and special hardware [7]- [9]. To analyze a microwave device a mathematical model based on a particular numerical method should be created.…”

“…Parallel computations in this algorithm are organized according to both -data parallelism and task parallelism paradigms. Efficiency of the proposed algorithm, and parallel algorithm based on Monte Carlo method [7], are compared.…”

The Influence of Non-Uniformity of the Multi-Conductor Line Parameters on Frequency Responses of the Meander Delay Line

“…Thus electrodynamic DLs have periodic structure with a specific repetition period of the meander strips or helical loops; therefore the multiconductor line method is widely used for the analysis and modelling of such lines [15]. The multi-conductor line method is notable for its modest demand of computer resources, which is very important for DL synthesis [14][15][16]. According to this method the multiconductor line and the corresponding Manuscript analysed DL are both periodic, therefore theoretically infinite, and consist of the infinite number of evenly spaced conductors of equal widths.…”
