Abstract: A tunable third‐order bandpass filter (BPF) with constant fractional bandwidth (CFBW) is presented. Only two quarter‐wavelength resonators have been used in comb‐line fashion to design the third‐order BPF. The physical dimensions of the resonators have… read more here.

Abstract: Abstract Sound absorption at low to moderate frequencies using quarter-wavelength resonators requires significant resonator's length (for instance 28 cm for 300 Hz), a condition very often uncompatible with a practical use of this kind of resonators for… read more here.
