Abstract: An aerosol-generating device for heating an aerosol-forming substrate to generate an aerosol is provided, the aerosol-generating device including: a substrate cavity configured to receive an aerosol-forming substrate; and an electromagnetic field generator including a solid state radio frequency (RF) transistor and being configured to generate a RF electromagnetic field in the substrate cavity. A method for generating an aerosol from an aerosol-forming substrate is also provided. An aerosol-generating article is also provided.

Abstract: The invention relates to a method for optical analysis of a component of an aerosol generating article, the method comprising:—providing a component of an aerosol generating article defining a first end and a second end, the component comprising: o an aerosol forming substrate; o a susceptor in thermal contact with the aerosol forming substrate;—providing a first polarized camera including a sensor to detect polarization information of electromagnetic radiation;—illuminating the component by electromagnetic radiation;—detecting transmitted, infected or refracted electromagnetic radiation from the component by the first polarized camera; —generating a first image of the first end of the component by the first polarized camera, the first image being formed by a plurality of pixels, each pixel of the plurality of pixels containing polarization information about the detected electromagnetic radiation; and—detecting in the first image a position of the susceptor.

Abstract: The invention relates to a method for checking an aerosol-generating article for manufacturing defects, comprising: —recording several 2-dimensional surface profiles of the aerosol-generating article while rotating the aerosol-generating article, —combining several surface profiles recorded at different rotation angles to obtain a 3-dimensional surface profile, calculating a maximum height difference of the 3-dimensional surface profile, and —rejecting the aerosol-generating article if the maximum height difference of its 3-dimensional surface profile is above a threshold value.
