Abstract
A novel tunable microwave broadband resonator, inspired from optical laser systems,
is presented. In contrast to usual harmonic resonators, the proposed device is based on
broadband composite right/left handed metamaterial lines. This line, configured as a
resonator, provides nonuniform spectral resonances due to the nonlinear nature of its
dispersion curve. This is exploited in the impulse regime, where the input pulse spectrum
is discretized inside the resonator, with different spectral separation as a function of the
carrier frequency. This discretization leads to a pulse periodicity in time, with a tunable
output time period. On the basis of the new broadband resonator features, a pulse rate
multiplication device is proposed. This device provides an increase in the repetition rate of
a periodic input pulse, with the additional advantage of repetition rate tunability.
