Equivalent Circuit Approach for Practical Applications of Meander-Line Gratings Molero Jiménez, Carlos García-Vigueras, María Rodríguez-Berral, Raúl Mesa, Francisco Llombart, Nuria Absorbers Circuit Models (CMs) Meander Lines Periodic Structures Polarizers This work was supported in part by Rennes Métropole for the funds AIS 17C0481 and in part by Region Bretagne for the contract SAD 2016 9637 as well as the Spanish Ministerio de Economía y Competitividad with European Union FEDER funds (Project TEC2013-41913-P). This manuscript reports an analytical circuit model to characterize periodic arrangements of printed meander lines. The methodology employed for the derivation of the model is presented together with two typical examples of its possible application: a polarizer and an absorber. Comparisons with results provided by a commercial software evidence the good accuracy provided by the equivalent circuit. 2025-01-28T09:42:13Z 2025-01-28T09:42:13Z 2017 journal article Published version: C.
