Abstract
We present a family of resonators which have harmonic resonance frequencies but in which some resonances are missing. Each resonator is composed by a succession of N cylinders of the same length. The cross-section area of each cylinder is equal to i(i+1)/2 times the cross-section area of the first cylinder (for i=1 to N) and the last cylinder in open. All the resonance frequencies are harmonic with F1 the lowest resonance frequency. However all multiples of (N+1)F1 correspond to antiresonance frequencies.
