An aerosol generation device is provided. The device is configured to heat an aerosol-generating product to generate an aerosol. The device includes a plasma generator configured to generate plasma to heat the aerosol-generating product through the plasma. In the aerosol generation devices, the plasma generator provides the plasma to the aerosol-generating product to heat the aerosol-generating product.

A measurement apparatus for alternating currents and voltages of a physical plasma ignited by applying an alternating high voltage from an alternating high voltage source to a plasma electrode via a high voltage line comprises a current transformer having a measurement winding on a ring core and a cable guide guiding the high voltage line through the ring core. A first measurement alternating voltage dropping over a measurement resistor connected between ends of the measurement winding is a first strictly monotonic increasing function of an amperage of the alternating currents flowing through the high voltage line. A second measurement voltage dropping over a measurement capacitance connected between a center tap of the measurement winding and a reference potential connector is a second strictly monotonic increasing function of an amplitude of the alternating high voltage applied to the plasma electrode with respect to a reference potential at the reference potential connector.

The dielectric barrier discharge plasma generator includes: a dielectric substrate that exhibits a plate shape extending in a first direction and has a first surface and a second surface located on an opposite side of the first surface in a second direction orthogonal to the first direction; a first electrode disposed on the dielectric substrate on a side of the first surface; a second electrode disposed at a position separated from the second surface of the dielectric substrate in the second direction; a gas flow path that is formed by a gap between the dielectric substrate and the second electrode and through which a gas flows in a third direction orthogonal to the first direction and the second direction; and an outlet provided at a first end which is one end portion of the gas flow path in the third direction.
