Abstract
A spherical resonator device includes a resonant sphere around which transducers for electrical coupling are metallized layers on a flat surface shaped to provide exposure of a sphere to a quasi constant field. In particular, the pattern comprises a transmission line of non-constant width in the region proximate to the sphere where a taper is provided which increases in width with distance from the sphere.

A spherical resonator device comprising:
- a resonant sphere;
- at least one transducer for electromagnetic coupling to said resonant sphere, said transducer comprising a flat metallized layer having a finite width shaped to provide exposure of the sphere to a quasi constant field,
- wherein said at least one transducer comprises a first region having a first width and a second region having a second width and a transition region between said first region and said second region, said first region being adjacent said resonant sphere, said first width being at a minimum, said second region being displaced radially from said resonant sphere, said second width being at a maximum, said transition region bridging between said first region and second region.
