1. An aerosol-generating device for heating a smokable material to generate an aerosol for inhalation, comprising:
a chamber for receiving a smokable material; and
an infrared emitter configured to radiate infrared rays toward the chamber to heat the smokable material;
wherein the infrared emitter comprises;
at least one first infrared emission region and at least one second infrared emission region arranged in sequence along a circumferential direction of the chamber; wherein the first infrared emission region and the second infrared emission region are configured to be independently activatable so as to independently radiate infrared rays to heat different portions of the smokable material; and
a substrate configured to surround a periphery of the chamber; and
wherein the first infrared emission region and the second infrared emission region are successively disposed on a substrate surface along the circumferential direction of the chamber for heating the smokable material received in the chamber.
