Zusammenfassung: 
A theoretical study of parametric amplification in magnetoinductive waveguides comprising metamaterial elements is presented. It is shown that phase-matching conditions can be satisfied in coupled waveguides by tailoring the dispersion characteristic of magnetoinductive waves. The corresponding formulation for parametric amplification is developed ab initio and analysed for a number of special cases. The problem of loss compensation in metamaterials by means of parametric amplification of magnetoinductive waves is studied in more detail.
