... radius . Computationally , the defect was introduced by varying the dielectric constant of a single column . In terms of the index of refraction n = √ , the defect varied from An = Nalumina — Ndefect = : 0 to An 2 ( one column ...
... radius r/a Figure 16: The evolution of localized modes associated with a defect column in an otherwise perfect square lattice with the parameters of figure 2, as the defect's radius is changed. A radius of r =0.2a corresponds to the ...
... radius r of a single rod has been changed . The rods are shown as dashed green outlines . Top left : a monopole ... radius r = 0.34a , which is doubly degenerate with the other state ( not shown ) formed by a 90 ° rotation . Middle row ...
... radius of the tubes or spheres), which maximize the width of the band gap, vary with the dielectric contrast. Examples of such results can be found in appendix C. Crystals. with. Complete. Band. Gaps. The possibility of three-dimensional ...
... radius of each sphere is large enough to cause the spheres to overlap . This removes the need for any connecting " bonds . " It was found that a complete photonic band gap exists whether one embeds dielectric spheres in air or air ...
