Fig. 3From: Omnidirectional Absorber by the Void Plasmon Effect in the Visible Region with Greatly Enhanced Localized Electric FieldCalculated absorption contours of the proposed nanohole array-based absorber as a function of wavelength and incident angle: a TE and b TM polarization. Here, the structural parameters of the absorber are set as p = 200 nm, w = 60 nm, h1 = 20 nm, h2 = 250 nm, and h3 = 200 nmBack to article page
