1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:

The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.

There is provided an aerosol-generating device (100) comprising a housing (110) having a chamber (120) sized to receive at least a portion of an aerosol-forming substrate, the chamber defining a heating zone. The aerosol-generating device (100) also comprises a first coil (131, 441) and a second coil (132, 435) disposed at least partially around, or adjacent to, the heating zone. The first coil is a drive coil couplable to a source of alternating current, and the second coil is a resonant coil of a resonant circuit, the second coil being inductively couplable to the first coil. In use, the coils operate to produce an enhanced magnetic field strength to efficiently heat a susceptor located within that magnetic field.

6. Drawings
The figure of the drawings to be published with the abstract is Figure No.     8    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
