(a) Absorptance spectrum (in blue) for a TM polarized light incident on a structure whose unit cell has size a_x  = 600 nm, and consists of a single column of 19 Rh rods separated by a_y  = 250 nm. The red curve corresponds to the absorptance spectrum when the rods having  are removed. (b) 2D color contour plot for the normalized volume density of power dissipation () in the case of a TM polarized light of frequency f = 440 THz incident on the structure mentioned in (a), before removing any rods.
