Abstract: A method of controlling an inductive heating arrangement is provided. The inductive heating system comprising an inductor and a susceptor coupled to the inductor so that the provision of an alternating electrical current to the inductor causes heating of the susceptor. The method comprises: providing pulses of electrical current to the at least one inductor to maintain a conductance or resistance associated with the susceptor at a target conductance or resistance; detecting a cooling event associated with the susceptor; determining a maximum duty cycle limit for the pulses of electrical current for a duration of the cooling event; and increasing a duty cycle of the pulses of electrical current for the duration of the detected cooling event, to compensate for the detected cooling event, to a duty cycle at or below the maximum duty cycle limit.

Abstract: An article 1 for use with a non-combustible aerosol-provision device comprises at least one fluid-permeable susceptor plug 4 and an aerosol-generating material 3 bounded by a wrapper 5. In some embodiments, the article comprises more than one aerosol-generating sections (3a-e) separated by one or more fluid-permeable susceptor plugs (4a-c). The plug (4') may comprise a body (15') made of susceptor material provided with a plurality of channels (16) to allow fluid to pass through the body (15') or the plug may be porous. In some embodiments the plug (4'', 4'') is made from a first material (15'') with one or more discrete portions (18, 19) of susceptor material distributed through out the first material.
