Ultrawideband Balanced Bandpass Filter
IEEE Microwave and Wireless Components Letters, 2011A broadside-coupled structure is utilized to design balanced bandpass filter (BPF) with ultrawideband performance. The top and bottom layers of the structure contain tapered microstrip patches. Those patches are coupled via tapered slots in the ground plane, which is located at the middle layer.

White light images are used to perform real-time spatial filtering in BaTiO3 in two different geometries. White light images act as spatial filters by erasing certain frequency components of photorefractive Fourier transform holograms. As a result, these frequency components are suppressed in the reconstructed holographic images.

Bandpass Filters for Communications
Optical Interference Coatings, 1995There is considerable interest today for filters for fiber optics telecommunications are in the Near Infra-red spectral area. Activity is centered about 1550 nm. Components for Wavelength Division Multiplexer filters used with fiber amplifiers require very high transmission of certain selected wavelengths with very low transmission of an adjacent ...

Zolotarev rational functions may be used in certain bandpass filter applications for which two narrower passbands are required. Coupled-resonator low-pass prototypes for narrow bandpass filters based on even- and odd-degree Zolotarev functions are synthesized using a transformed variable.
