(a) TEM, TM and TE modal dispersion curves for the studied unperturbed structures (εr1[2] = 10.2[3], h1[2] = 1.27[1.52] mm). Green color, single-layer GDS (1L-GDS) (b) TM0 (solid line), TE1 (dashed line). Cyan color, 2L-GDS (c) TM0 (solid line), TE1 (dashed line). Black lines, 2L-PPW (d) quasi-TEM (solid line), TE1/TM1 (dotted line). Red lines, single-layer PPW (e) TEM (solid line), TE1/TM1 (dashed line).
