(a) Extinction cross section spectrum for a lossless single cylindrical particle with the refractive index of 2.95 and diameter (D 0) of 11.4 mm. The inset shows the schematic of a cylindrical dielectric particle with incident light propagating along the x axis. The diameter and height of the particle are identical as D 0. Various Mie resonance modes (electric and magnetic dipole modes and their higher-order modes) are present; MD (magnetic dipole), ED (electric dipole), MQ (magnetic quadrupole), EQ (electric quadrupole), and MH (magnetic hexapole). (b) Top (bottom) panels represent the E z component of each Mie resonance mode on the xy (yz) plane. Higher order modes generally exhibit sharper resonance peaks in the spectrum, and they have more nodes (i.e., zero field lines) in the field distribution.
