Abstract
A method for determining whether a susceptor is changed, according to one embodiment, may comprise the operations of: applying a first signal to a coil of a heater so as to generate an alternating magnetic field having a first frequency; determining a first value of an electrical characteristic of the susceptor indicated by the first signal; applying a second signal to the coil of the heater so as to generate an alternating magnetic field having a second frequency; determining a second value of an electrical characteristic of the susceptor indicated by the second signal; and determining whether the susceptor is a changed susceptor, on the basis of the first value and the second value.

A method of determining a susceptor change performed by an aerosol generating device, the method comprising:
- applying a first signal to a coil of a heater such that an alternating magnetic field having a first frequency is generated;
- determining a first value of an electrical characteristic of a susceptor indicated by the first signal;
- applying a second signal to the coil of the heater such that an alternating magnetic field having a second frequency is generated;
- determining a second value of an electrical characteristic of the susceptor indicated by the second signal;
- and
- determining whether the susceptor is a changed susceptor based on the first value and the second value.
An aerosol generating device, comprising:
- a coil configured to generate an alternating magnetic field;
- and
- a controller controlling the aerosol generating device,
- wherein the controller is configured to:
- apply a first signal to the coil such that an alternating magnetic field having a first frequency is generated;
- determine a first value of an electrical characteristic of a susceptor indicated by the first signal;
- apply a second signal to the coil such that an alternating magnetic field having a second frequency is generated;
- determine a second value of an electrical characteristic of the susceptor indicated by the second signal;
- and
- determine whether the susceptor is a changed susceptor based on the first value and the second value.
