摘要： A method for matching an impedance of a system comprising a cavity and one or more feeds to an impedance of one or more sources of electromagnetic radiation irradiating a plurality of frequencies into the cavity via the feeds, comprising: determining a plurality of s-parameter of the system for a frequency band; determining the system impedance based on the s-parameters; and modifying the system impedance according to the difference between the impedance of the system and the impedance of the source.

摘要： An apparatus for exciting a rotating field pattern in a cavity containing an object, the apparatus comprising a radiating element configured to excite an electromagnetic (EM) field pattern in the cavity, wherein the EM field pattern is excited with EM energy at a frequency in the radio-frequency (RF) range, a field rotating element configured to rotate the EM field pattern, wherein the field rotating element has an anisotropy, the anisotropy selected from magnetic anisotropy, electric anisotropy, and a combination of magnetic and electric anisotropies, and a controller configured to determine the EM field pattern according to value indicative of energy absorbable by the object and to control the anisotropy of the field rotating element in order to rotate the EM field pattern.
