A simple and efficient transmission line model is proposed here to study how the transmission characteristics of photonic crystal waveguides are tailored by introduction of stubs patterned in the photonic crystal lattice. It is shown that band-pass and band-stop optical filters can be easily designed and optimized when stubs of appropriate length are brought in. Since the lengths of the designe...

The transmission line method (TLM) is almost ideally suited for computation of wave propagation in the presence of various media as well as to the representation of sources, including antennas. Being a time domain method, it requires few assumption on the shape or frequency of the source waveform. It can handle a variety of interface conditions as well as material properties including lossy med...
