| |PDF (160 KB) | HTML

In the analysis of open planar structures, it is widely accepted that the spectral decomposition of the fields excited by a given source into its continuous and discrete spectrum components has an apparent physical meaning. The continuous spectrum is associated with radiation and/or reactive effects whereas the discrete spectrum corresponds to the bound fields guided by the structure. Although thi...

A dual-mode dual-band bandpass filter with two transmission poles in both passbands using a single ring resonator is proposed. Two excited ports are placed at the 135deg -separated positions along the ring resonator and coupled with the ring via parallel-coupled lines, leading to synchronous excitation of two transmission poles in dual passbands. After the principle of this initial filt... View full abstract»
