Abstract
An aerosol-generating device is provided, including a housing defining a chamber having an open end configured for insertion of an aerosol-generating article into the chamber and a closed end disposed opposite the open end; a flat spiral inductor coil disposed at the closed end of the chamber; a susceptor element disposed within the chamber at the closed end; and a power supply and a controller connected to the flat spiral inductor coil and configured to provide an alternating electric current to the flat spiral inductor coil such that the flat spiral inductor coil is configured to generate an alternating magnetic field to inductively heat the susceptor element and thereby to heat at least a portion of an aerosol-generating article received within the chamber.
