Synthesis of coupled resonator circuits with multiple outputs using coupling matrix optimization
… that can achieve Chebyshev and Quasi-elliptic filtering responses. To verify the design methodology, some components with Chebyshev filtering response have been designed, fabricated and tested. X-band coupled resonator devices have been realized using waveguide cavities: 3-dB power divider, …

Suspended stripline filters for ultrawide bandwidth and high RF power
… specifications was used to realise a UWB filtering response. Optimum high-pass filters were synthesised, and filters were synthesised using Z plane synthesis, with designs ranging from 2 to 13 GHz. In addition, a multilayer quasi-lumped suspended stripline filter was designed. The filters …

The Feeding ecology of, and carbon and nitrogen budgets for, sardine sardinops sagax in the Southern Benguela upwelling ecosystem
… food particles <1230μm total length eliciting a filtering response while larger particles elicit particulate-feeding at low concentrations and filter-feeding at high concentrations. This species is able to retain cells as small as 13μm, feeds at near-maximum efficiency when filterfeeding, and …

Ultrawideband and Multi-state Reconfigurable Antennas with Sum and Difference Radiation Patterns
… with multistate frequency-reconfigurable filtering functions in a series of novel designs. In the first proposed design, two quasi-Yagi-Uda antennas are used for pattern diversity, while two switchable and reconfigurable bandpass-to-bandstop filters are used to excite the antenna elements. …
