Abstract
An aerosol-generating device is provided, including: a housing having a chamber configured to receive at least a portion of an aerosol-generating article; an inductor coil disposed around at least a portion of the chamber; a plurality of elongate susceptor elements projecting into the chamber and spaced apart from each other, the susceptor elements each extending substantially parallel to a magnetic axis of the inductor coil; and a power supply and a controller connected to the inductor coil and configured to provide an alternating electric current to the inductor coil such that the inductor coil generates an alternating magnetic field to heat the susceptor elements and thereby heat at least a portion of the article received in the chamber, the inductor coil being helical and having a non-circular cross-sectional shape. An aerosol-generating system including the device, the article, and the susceptor elements, is also provided.
