(a) Electric field distributions of defect modes resonating at Dwarf Dirac points for k_z = 0.50/Λ, calculated by eigen-frequency solver. (b) Result of mode solution at the same frequency as that in the case of panel (a). (c) Electric field |E| pattern in the x–z plane for the same case. Scales in figures are in micron and the colour bar indicates the highest magnitude of electric field norm in red and the lowest in blue.
