In this paper, the power dissipated through different loss mechanisms including dielectric, conductor and radiation loss is calculated for the substrate integrated waveguide (SIW) and modified substrate integrated waveguide (MSIW). The applied computational method being appropriate for structures with periodic conducting parts allows one to calculate the integrals corresponding to these powers ...

A novel method of using bypass coupling SICC resonator to generate transmission zeros in filter stopband to improve stopband attenuation is presented.
