28 Claims

1. An aerosol generating device comprising:

an induction heating circuit for inductively heating a susceptor arrangement to heat an aerosol generating material to thereby generate an aerosol;

wherein the aerosol generating device is configured such that during operation a level of electromagnetic radiation emitted by the aerosol generating device is at least one of:

less than 40 dBμV/m over a frequency range of 30 MHz to 225 MHz, less than 47 dBμV/m over a frequency range of 235 MHz to 1 GHz, less than 70 dBμV/m over a frequency range of 1 GHz to 3 GHZ, or less than 74 dBμV/m over a frequency range of 3 GHz to 6 GHZ,

wherein the aerosol generating device comprises a magnetic shield member configured to extend at least partially around the induction heating circuit or the susceptor arrangement.
