Design Of A Catenoidal Shaped Anechoic Termination, Kyle Myers
Masters Theses
An analytical model is developed in this thesis to predict the reflection coefficient of an anechoic termination consisting of a catenoidal horn connected to a tube lined with absorbing material. The theoretical predictions are compared to experimental measurements on a prototype. Comparisons are made for a variety of arrangements, including, an open horn, and a horn connected to absorbing terminations of two different lengths. The absorbing terminations are either open or closed to the environment and the analytical model can account for both these scenarios. The results indicate that the new model can accurately predict the reflection coefficient for each …
