FIG. 1.

Experimentally obtained dispersion curves (symbols) of surface mode supported by samples with L = 100 mm and 1.60 mm compared with analytically derived dispersion (lines) for a structure represented by inset schematic. Pitch d = 1.59 mm, Height H = 3.75 mm, a = d/2, near field source to detector length P = 775 mm, lateral widths L are varied.

FIG. 2.

Numerical simulations of time averaged electric field (gray scale, arbitrary units) and vector magnetic field (arrows) on resonance of the domino waveguide consisting of open-ended cavities (a) and closed-ended cavities (b).

Image of FIG. 3.
FIG. 3.

Dispersion curves obtained experimentally are represented by the symbols ○, ⋇ and Δ which indicate data from the L = 100 mm closed-ended, L = 10 mm open-ended and L = 10 mm closed-ended structures respectively. Data obtained numerically (FEM) are represented by the short dotted line and long dashed line for the L = 10 mm open and closed-ended structures, respectively. The solid black line represents the light line and the intermittently dotted black line is the domino-cavity resonance. Inset is a schematic of the modified domino structure, the gray sides representing the closed boundary condition.
