“…As simulações foram realizadas no domínio tempo [CST ® ]. O CST, para obtenção dos resultados numéricos, utilizou um modelo de malha composta por elementos hexaédricos, pois a mesma é recomendada para lidar com diversos tipos de estruturas complexas [Hirtenfelder & Lubkowski, 2007]. A fonte de campo utilizada foi uma onda plana com amplitude de campo elétrico de 10 V/m na direção "x" e direção de propagação em "y".…”

“…We have compared the mutual coupling between two horizontally-polarized ACMAs printed on the grounded dielectric slab with and without metal grating structure between the antennas. For this purpose, we have used the Finite Integration Technique (FIT) [23]. Figure 8 shows the coupling coefficient S 21 between both antennas for the optimized metal grating structure, with only three metal strips between both antennas.…”

“…In both cases, the ground-plane size is 150×150 mm 2 . The simulation of the complete structure was done with a FIT technique [23]. From Figure 11 Figure 10.…”

“…The MTM macrostructure analysed in this paper is a MTM lattice of a parabolic shape, which due to its DNG properties leads to an unusual phenomenon [16]. With a negative index of refraction, the refracted wave occurs on the same side of the normal to the boundary as the incident wave, which leads to the focusing of waves in the DNG frequency range.…”
