(a) Power dissipation rate corresponding to different frequency and normalized in-plan wavevector. Inset: Power dissipation spectrum for  = 3.0 eV, wavevector intervals represent radiation, SPP, and lossy surface wave, respectively. (b) Total dissipation rate, coupling into radiation, SPP, and lossy mode are denoted by solid, dashed, dotted, and dashed-dotted lines, respectively. Ratio of SPP mode is represented by blue line.
