Designing asymmetric multilayered membrane filters with improved performance

UWB-Bandpass Filters with Improved Stopband Performance

Performance Analysis of Multilayered Multipriority Asymmetric-Sized Delta Networks

The performance ofmultilayered asymmetric-sized finite-buffered delta networks supportingmulticlass routing traffic is presented and analyzed in the uniform traffic conditions under various loads using simulations. The rationale behind introducing asymmetric-sized buffered systems is to have a better exploitation of available buffer spaces, while the implementation of multilayered architecture ...

Asymmetric membrane filters for the removal of leukocytes from blood.

As part of a study on the mechanisms of leukocyte filtration, the influence of pore size distribution on filter efficiency was investigated. Conventional leukocyte filters are not suitable for model studies, as these filters are composed of tightly packed synthetic fibers, with a poorly defined porous structure. Therefore, open cellular polyurethane membranes with pore size distributions varyin...

Very narrow spectral filters with multilayered grating-waveguide structures

Promising configurations for grating-waveguide structures are presented. In these structures, the grating layer, which is normally adjacent to the waveguide layer, is displaced by means of an intermediate layer, resulting in significant reduction of losses and weaker coupling. This leads to very narrow spectral bandwidths and high contrast ratios. Experimental results reveal that the spectral b...
