Abstract
A shisha system comprising an aerosol-generating article (90) and a shisha device (50). The aerosol-generating article (90) comprises an aerosol-forming substrate (92). The shisha system further comprises a first electrode (15) and a second electrode (16). The shisha device (50) comprises a liquid cavity (54) configured to contain a volume of liquid, the liquid cavity (54) having a head space outlet (60); an article cavity (14) configured to receive an aerosol-forming substrate (92), the article cavity (14) being in fluid communication with the liquid cavity (54). The shisha device further comprises an oscillation circuit (10) configured for connection to the first electrode (15) and the second electrode (16). The oscillation circuit (10) is configured to supply a radio frequency (RF) alternating voltage to the first electrode (15) and the second electrode (16), the RF voltage between the first electrode (15) and the second electrode (16) generating an alternating radio frequency (RF) electromagnetic field between the first electrode (15) and the second electrode (16) for heating the aerosol-forming substrate (92) when the aerosol-generating article (90) is received in the article …
