Red and black dots signify the nodes where the current is injected and extracted, respectively. The blue dashed square represents the physical N-unit cell 2D LC circuit, while the brown dashed square illustrates the 2N-unit cell supercircuit, which includes the image copies of the N-unit cell circuit along each principal direction.
