Exact Design of Band-Stop Microwave Filters
IEEE Transactions on Microwave Theory and Techniques, 1964An exact method for the design of band-stop filters which adapts synthesis techniques due to Ozaki and Ishii is discussed. This method places no theoretical limit on the width of the stop-band, although, for practical reasons, different (but equivalent) circuit configurations are used for stop-bands of different widths.These configurations include a ...

Terahertz frequency range band-stop filters
Applied Physics Letters, 2005We report the operation of band-stop filters in the terahertz (THz) frequency range, working at a center frequency of 600GHz. The filters were characterized by embedding them in a microstrip line attached to photoconductive switches which act as THz emitters and detectors. The filters have applications in sensing and detection. The chosen filter design

Comparison of several techniques for adaptive band-stop filters
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011Adaptive band-stop filters used for attenuation of narrow-band interference in spread-spectrum receivers or due to resonances in control systems and instrumentation are becoming more common as we pack more signals into limited bandwidth. Two techniques for implementing these adaptive band-stop filters include adaptive heterodyne filters and adaptive ...

Design of Band-Stop Filters in the Presence of Dissipation
IEEE Transactions on Microwave Theory and Techniques, 1965The insertion loss vs. frequency characteristic of equal-element band-stop filters is derived for large as well as small degrees of dissipation, and for any number of resonators. These results are presented as curves for one through eight resonator filters. The equal-element band-stop filter, for small dissipation, is shown to have the lowest pass-band

A Rectangular Dielectric Resonator Band Stop Filter
2006 IEEE Antennas and Propagation Society International Symposium, 2006A transmission mode band reject filter using TEXY/ mode of a rectangular dielectric resonator (DR) is discussed. The band reject filter characteristics of the DR operating in the TEXY/ mode, coupled to a microstrip line enclosed within a cylindrical cavity is studied.

The investigation results of K/sub L/ stop-band filter based on wave-slot line are represented. The principle characters of such structures are the high attenuation level in stopband (around 30-40 dB), relatively low attenuation level in a pass-band (it is within 2 dB) and ability for manufacture.

Band-Stop Filters For High-Power Applications
IEEE Transactions on Microwave Theory and Techniques, 1965There are several advantages to the use of band-stop filters, rather than band-pass filters, in many systems. This is shown to be particularly true when signals at high-power levels must be transmitted or rejected. A formula has been derived which expresses the external Q of each resonator in a band-stop filter in terms of the element values of the ...

A Tunable Absorbing Band-Stop Filter: The Field Rotation Filter
IEEE Transactions on Microwave Theory and Techniques, 1969A study has been made of the propagation of the first-order modes in a structure obtained by placing a thin magnetized ferrite slab against a broad wall of a rectangular waveguide. The numerical solution of the characteristic equation shows that, with a suitable choice of parameters, it is possible to realize an electrically tunable band-stop filter ...
