Circuito equivalente analítico basado en vectores y valores propios para superficies periódicas con ranuras estrechas. Hernández-Escobar, Alberto Mesa, Francisco Esteban, Jaime Abdo-Sánchez, María Elena Martín-Guerrero, Teresa María Camacho-Peñalosa, Carlos Antenas In this work, the values of the parameters of the eigenstate lattice network are obtained by using only analytical means. The procedure is applied to a simple structure, consisting of a bi-periodic surface made of a slotted metallic plane. The slot is very narrow and is slightly rotated. The analytical values are obtained by using a multi-mode expansion approach that only requires information about the normalized field in the slot. The equivalent circuit and the procedure are simple and provide physical insight into the structure. Very good agreement is found for analytical values and simulated ones. 2023-09-19T10:05:41Z 2023-09-19T10:05:41Z 2023 2023 conference output https://hdl.handle.net/10630/27574 spa URSI 2023 - XXXVIII Simposio Nacional de la Unión Científica Internacional de Radio Cáceres Septiembre 2023 open access
