Dielectric resonators - Microwave circuits

frequency tuning

Modification of the resonance frequency by a few percent around a central value.

microwave cavity; cavité micro-onde

Rectangular, cylindrical or spherical metal-walled cavity with resonance modes determined by the dimensions of the cavity.

cristaux photoniques ; photonic crystals

Periodic structures of 2 dielectrics.

quality factor

Ratio of stored energy to dissipated energy.

metamaterials; metamaterials :

Negative-index materials made from periodic structures of resonant objects (dielectric resonators, metal wires, split metal rings).

modes duaux ou triples; dual or triple modes

Degenerate propagation modes of order 2 or 3 for which the electromagnetic fields have the same spatial periodicity, but different configurations.

mode parasite; spurious mode

A mode that is close to the mode in use...
