these modes to the attenuation constant of the principal mode in a 

 completely filled Clogston 2. 



These results may be compared mth those given in Section IX for 

 the principal mode in plane Clogston lines having the same proportions. 

 Turning now to the cylindrical geometry, we remember that all the 

 circular transverse magnetic modes in a coaxial Clogston line "N^ith 

 infinitesimally thin laminae and high-impedance boundaries are given 

 by the roots of equation (339) of Section IX, namely 



KoKo{koPi) -\- io3€oZiKi{Kopl) _ KoKaiKoPi) — icii€oZ2Kl{KoP2) 

 Ko/o(koPi) — icO€oZiIi(KoPl) KoIo{K(iP2) + lOieoZ ol l{KoPi)
