1. A thickness measurement system (1) comprising:
a sensor (4) for measuring a thickness of a layer (3) coated on a body (2) by transmitting and/or reflecting electromagnetic signals, wherein the layer (3) improves physical properties of for the body (2) and/or provides protection against external factors for the body (2);
a processor unit (5) that receives and processes frequency data received from the sensor (4) to calculate a value of the thickness of the layer (3), wherein the sensor (4) comprises a metamaterial-based split-ring structure positioned a predetermined distance to the body (2); and
a plurality of ports (6) on the sensor (4) that allow frequency signal transfer therebetween;
wherein the processor unit (5) determines a frequency value at which a signal energy (E) transmitted between the ports (6) is minimum based on the frequency data received from the sensor (4), and matches the determined frequency value with a corresponding predetermined layer (3) thickness value so that the thickness of the layer (3) thickness value on the body (2) is determined in a contactless manner.
