Beamwidth Control of Multicellular Horns

  • John M. Eargle


The data presented in Figure 58 show the theoretical −6 dB beamwidth control of multicellular horns as a function of the number of cells in one plane. Note that for horns consisting of more cells, the useful frequency range extends lower. Just below that useful limit, the pattern control narrows greatly. This takes place at the frequency whose wavelength is approximately equal to the distance spanned by the group of cells. Below the frequency of narrowing, the pattern control becomes increasingly wide.
