The aerosol delivery device includes a resonant transformer comprising a resonant transmitter and a resonant receiver. The aerosol source member includes an inhalable substance medium at least a portion of which is positioned proximate the resonant transmitter. The resonant transmitter is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, such that the alternating voltage causes the resonant receiver to generate heat and thereby vaporize components of the inhalable substance medium to produce an aerosol. In some implementations, the resonant receiver comprises part of the control body. In other implementations, the resonant receiver comprises part of the aerosol source member. ## Claims ### Claim 1 An aerosol delivery device comprising: a control body; a resonant transmitter; and an aerosol source member that includes an inhalable substance medium and a resonant receiver, wherein the aerosol source member is configured to be insertable into the control body, wherein the resonant transmitter is located within the control body and is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, the alternating voltage causing the resonant receiver to generate heat and thereby vaporize components of the inhalable substance medium to produce an aerosol, wherein the resonant transmitter comprises a transmitter coil, wherein the control body further comprises a coil support member, and wherein the resonant receiver is located in an approximate center of the aerosol source member. ### Claim 2 (depends on 1) The aerosol delivery device of claim 1, wherein the aerosol source member defines a heated end, and wherein the approximate center of the aerosol source member comprises an approximate radial center of the heated end of the aerosol source member. ### Claim 3 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver comprises a receiver cylinder. ### Claim 4 (depends on 3) The aerosol delivery device of claim 3, wherein the receiver cylinder comprises a hollow receiver cylinder. ### Claim 5 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver comprises a braided wire structure. ### Claim 6 (depends on 5) The aerosol delivery device of claim 5, wherein inhalable substance medium comprises a tube structure defining an inner surface and an outer surface, and wherein the approximate center of the aerosol source member comprises an area between the inner and outer surfaces of the inhalable substance medium. ### Claim 7 (depends on 1) The aerosol delivery device of claim 1, wherein the inhalable substance medium comprises a solid or semi-solid medium. ### Claim 8 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver is constructed of one or more ferromagnetic materials. ### Claim 9 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver is constructed of one or more conductive materials. ### Claim 10 (depends on 1) The aerosol delivery device of claim 1, further comprising a power source located in the control body including one or more of a rechargeable supercapacitor, a rechargeable solid-state battery, and a rechargeable lithium-ion battery, the power source being configured to power the resonant transmitter. ### Claim 11 (depends on 10) The aerosol delivery device of claim 10, wherein the power source further includes terminals connectable with a source of energy from which the rechargeable power source is chargeable. ### Claim 12 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant transmitter is configured to at least partially surround the resonant receiver. ### Claim 13 (depends on 1) The aerosol delivery device of claim 1, wherein the inhalable substance medium comprises a tobacco material. ### Claim 14 (depends on 13) The aerosol delivery device of claim 13, wherein the inhalable substance medium comprises a reconstituted tobacco material. ### Claim 15 (depends on 1) The aerosol delivery device of claim 1 further comprising a foil material, wherein the foil material surrounds at least a portion of the coil support member. ### Claim 16 (depends on 1) The aerosol delivery device of claim 1, wherein the control body further comprises one or more light emitting diodes. ### Claim 17 (depends on 1) The aerosol delivery device of claim 1, wherein the control body includes an additional resonant receiver. ### Claim 18 (depends on 17) The aerosol delivery device of claim 17, wherein the additional resonant receiver comprises a hollow receiver cylinder. ### Claim 19 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver contacts the inhalable substance medium. ### Claim 20 (depends on 1) The aerosol delivery device of claim 1, wherein the resonant receiver does not contact the inhalable substance medium.
