Zusammenfassung: 
The problem of terminating a transmission line that consists of a set of coupled loop resonators to support the propagation of magneto-inductive waves is considered. Since the ideal terminating impedance is not easily realisable end-reflections are generally obtained from such a line. Techniques are developed to calculate the reflection coefficient from a line terminated with a finite number of lossy resonators. The effectiveness of a variety of absorbing modifications is compared, and it is shown that broadband reflection suppression may be obtained from a geometrically graded variation of attenuation.
