Patent ID: 7186377

Claim:
An apparatus for measuring absorbed power comprising: a phantom which has a configuration that simulates a configuration of a head of a human body, and which is made of a material having electromagnetic characteristics that simulate those of a human body or formed of a container filled with said material, the phantom including an opening at a first side surface portion, the opening providing access to a second side surface portion opposite to the first side surface portion and interior to the phantom; an electromagnetic field probe configured to measure a strength of an electric field or a magnetic field of a radio wave irradiated thereto, said probe being positioned in said phantom through the opening and retained in said phantom at or close to the second side surface portion of said phantom; a radio wave radiation source positioned exterior of said phantom adjacent to said second side surface portion for irradiating a radio wave to said probe retained interior of said phantom; and a calculation unit configured to estimate the power of the radio wave absorbed by the part of the human body on the basis of measured values from said probe; wherein said phantom has a volume which is equal to or less than ⅛ times the volume of the head of the human body.
