Abstract :
The propagation characteristics of a subwavelength grating (SWG) waveguide are analyzed by an efficient frequency domain finite element approach. An equivalent continuous waveguide has been obtained for several duty cycles and for a wide bandwidth. A comparison of their electric field spatial distribution has been performed through an overlapping integral. An equivalent continuous waveguide can be considered for the analysis of SWGs.
