The device wave trapping property was verified by the input of an ac signal in the suitable frequency domain and found to behave as an ideal narrow band stop filter with promising features for use in microwave communication technology.
But from the simulation results can be seen as a narrow band stop filter its characteristics is poor, in the future work should be further optimized.
If the H (s) has been directly transferred to the needed simulative low pass, high pass, band pass and band stop filter, then the [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] of low pass filtering is the needed low pass filter's cut-off frequency.
This paper proposes a new design of dual-band band stop filter (DBBSF) using coplanar waveguide (CPW) technology.
