(a,b) Simulated and circuit-modeled transmission amplitudes for VO₂ in its dielectric (monoclinic) and metallic (tetragonal) phases, respectively, including their circuit representations. (c) Unit cell MM with its equivalent lumped circuital model. (d) Circuital model of the multistacked MM without the VO₂ layer, and (e) its corresponding simulated and calculated transmission amplitude. (f,h) Equivalent circuit representations of the multistacked MM when VO₂ is in the dielectric and metallic phases, respectively. (g,i) Corresponding transmission amplitudes fitted with circuit theory for the dielectric (DP) and metallic phases (MP).
