The extinction spectrum of the nanoegg and the Au sphere. (a) The multipolar extinction spectra of the nanoegg with different core offset D at R 1/R 2 = 36 nm/46 nm. Various colored shapes indicate the peak wavelengths of multipolar extinction spectra (red circles, l = 1; green squares, l = 2; purple triangles, l = 3; blue diamond, l = 4). (b) The extinction spectrum of the Au sphere with different radius r 1.
