BirdcageBuilder Mobile

A radio-frequency coil inductance and capacitor calculator for Android.

We are making available an Android version of BirdcageBuilder.

[For a new, open-source, web-based version of BirdcageBuilder, see Open BirdcageBuilder.]

Birdcage radio-frequency (RF) coils are resonant circuits that operate with a specific current pattern at particular frequencies and are tuned by choosing the proper capacitor values.

BirdcageBuilder Mobile offers an interface for determining mutual inductances and capacitors needed to make a coil resonate at a particular frequency, given the coil’s geometric properties such as the length and number of legs, cross-sectional shape of legs and end-rings, and the radii of the coil and shield.
