It is, however, worthwhile to quote results analogous to Eq. (8.23) for the throat
impedance of a truncated conical or exponential horn terminated by a given
mouth impedance ZL, which is typically the radiation impedance, though this
requires ...

The normalized delay of an exponential horn is plotted as a function of a in
