Abstract: An inflatable high Q toroidal inductor is fabricated from an inflatable tidal-shaped shell made from a flexible material provided with a fitting adapted to receive and vent pressurized gas. A pair of flexible strips are disposed on opposite sides of the inflatable toroidal-shaped shell to hold litz windings in a predetermined toroidal configuration to thereby provide a suitable inductor of high Q and low loss. The inductor may be compactly carried to a remote instrumentation site, inflated and used and then deflated, folded and taken to the next site for reuse.
