Abstract:
1. A specific absorption rate measuring system for evaluating absorption of electromagnetic wave energy, comprising: a biological tissue equivalent phantom for absorbing electromagnetic wave energy; two or more electro-optical crystals that are arranged at two or more measurement points in the biological tissue equivalent phantom, the electro-optical crystals having a dielectric constant approximately equal to the dielectric constant of the biological tissue equivalent phantom; two or more optical fibers laid in the biological tissue equivalent phantom for coupling each of the electro-optical crystals to an external destination; and a specific absorption rate measurement unit configured to determine a specific absorption rate of the biological tissue equivalent phantom, based on the response of the electro-optical crystals conveyed thereto via the two or more optical fibers wherein the specific absorption rate measurement unit derives a specific absorption rate (SAR) of the biological tissue equivalent phantom, the SAR being defined by an equation that is a function of a conductivity σ of the biological tissue equivalent phantom, a density ρ of the biological tissue equivalent phantom, a constant K determined by the crystallographic axis of the electro-optical crystals, and a phase difference Γ.
