| description abstract | Automatic control of an oil well drilling process requires the knowledge of the dynamics of signal propagation through the annulus formed between the drill and the casing. This paper extends work previously done for circular lines to the annular case. Attenuation and phase speed are presented for various radius ratios as a function of signal frequency. For the liquid case, the results are correlated through the use of an equivalent radius. | |
