1. An inductive heating element for an aerosol-generating system, the inductive heating element comprising:
a cavity configured to receive an aerosol-forming substrate to be heated by the inductive heating element;
a first susceptor;
a second susceptor;
an intermediate element disposed between the first susceptor and the second susceptor, the intermediate element being gas permeable,
wherein the intermediate element comprises at least one of:
a thermally insulative material configured to thermally insulate the first susceptor from the second susceptor, and
an electrically insulative material configured to electrically insulate the first susceptor from the second susceptor; and
a flux concentrator, a portion of the flux concentrator extending into the intermediate element between the first susceptor and the second susceptor.
