    摘要： The invention relates to a device and method for measuring an electromagnetic dosimetric quantity received by an object illuminated by an electromagnetic (EM) field (23) emitted by an electromagnetic source (2), comprising:
    - a screen (3) comprising a top surface (31) faced to the electromagnetic source (2) and a bottom surface (32) opposite to the top surface (31), said screen (3) being adapted to absorb at least a portion of the EM field emitted by the electromagnetic source (2);
    - the screen comprising a plurality unit cells (33);
    - at least one thermal sensor (5) arranged relative to the bottom surface of the screen (3) and configured to measure a physical quantity relative to the heat distribution along a surface of the screen induced due to the absorption of the electromagnetic field in the screen medium;
    - a processing unit (6) linked to the at least one thermal sensor (5) and configured to calculate the electromagnetic dosimetric quantities from the measured heat distribution, the information relative to the EM field emitted by the EM source, and the predetermined EM and thermal properties of the screen.
