The E-field distribution along x-axis from x = 0 mm to x = 360 mm, with a height of 3 mm above the upsurface of structure.
(a) The E-field distribution of the periodically modulated grooved structure. (b) The E-field distribution along the structure with constant groove depth and h = 2 mm for each grooves.
