Abstract :
In this study a low-cost, compact, and high-performing metamaterial-based biosensor operating in the GHz regime is presented. The sensor is designed to detect the presence of a tumor by means of permittivity and absorption measurements. A shift in the position of the sensor response and in the amplitude width is related to the different permittivity and absorption values of the malignant and normal tissues, respectively.
