Permittivity based temperature measurement and related methods
First Claim
1. A method for determining temperature of a material comprising:
- measuring at least one of the real and imaginary parts of the permittivity of the material at each of at least one frequency for which substantially only a single known component of the material contributes to the dielectric permittivity of the material, for which known component the permittivity as a function of temperature is known; and
using at least one of the determined real and imaginary part of the permittivity at each of the at least one frequency and the dependence of the permittivity of the known component on temperature to determine temperature of the known component and thereby of the material.

Abstract
A method for determining temperature of a material (32) comprising: measuring at least one of the real and imaginary part of the permittivity of the material (32) at each of at least one frequency (36) for which substantially only a single component of the material contributes to the dielectric permittivity of the material (32), for which known component the permittivity as a function of temperature is known; and using at least one of the determined real and imaginary part of the permittivity at each of the at least one frequency and the dependence of the permittivity of the known component on temperature to determine temperature of the known component and thereby of the material (32).

27. A method for determining an amount of radiation absorbed by a material comprising:
-
illuminating the material with the radiation between a first time and a second time;
measuring at least one of the real and imaginary parts of the permittivity of the material at first and second temperatures at each of at least one frequency for which substantially only at least one known component of the material contributes to the dielectric permittivity of the material, wherein for each of the at least one known component the permittivity as a function of temperature is known aid concentration of the component relative to the others of the at least one known component is known;
