Abstract
A heater assembly for an aerosol-generating system is provided, the heater assembly including: a liquid aerosol-forming substrate including at least two compounds, the first compound having a first boiling point and the second compound having a second boiling point; a retention material containing the liquid aerosol-forming substrate; and a heating element configured to heat the retention material by passing a current along a length of the heating element, the heating element being formed from a band of material, and a cross-sectional area of the band of material progressively decreasing along a length of the band of material from a maximum cross-sectional area of the band of material at a first end of the band of material to a minimum cross-sectional area of the band of material at a second end of the band of material, to provide a temperature gradient along a surface of the retention material.
