Abstract
A selective heating device comprises a chamber configured to contain a target to be at least partially heated, an active electromagnetic (EM) element to generate an electromagnetic field in the chamber and a passive EM element in the chamber. The passive EM element is capable of electromagnetically coupling to the active element. The active EM element and passive EM element are controllable to selectively heat a portion of the target.
Claims19
A selective heating device comprising:
- a chamber configured to contain a target to be at least partially heated;
- an active electromagnetic (EM) element;
- a first passive EM element in the chamber, the first passive EM element capable of electromagnetically coupling to the active EM element and having a first passive EM element polarization, wherein the active EM element and first passive EM element are controllable to selectively heat a portion of the target and wherein the active EM element is controllable to generate, in the chamber, a first electromagnetic field having a first electromagnetic field polarization that aligns with the first passive EM element polarization;
- and
- a second passive EM element in the chamber, the second passive EM element configurable to have a second passive EM element polarization that is different than the first passive EM element polarization, the second passive EM element configurable to couple to a second electromagnetic field that aligns with the second passive EM element polarization.
