a Sketch of the strip-loaded slot waveguide. b Power distribution of transverse magnetic modes in the structure. The simulations have been performed for illustration purpose, which means that the strip dimensions have been increased to allow either TM10 or TM01 modes to propagate. c Mode profiles for TM00 in y- and x-directions (indicated by arrows on the TM00 power distribution)
