a The measured near-field power density incident by Infineon radar transmitter (TX) antenna inside the phantom, beaker filled with pure water, in the presence or absence of the designed transmissive metasurface. b The investigation of the measured power reflected from the phantom, received by the radar receiver antenna (RX3), over a period in the presence or absence of the designed transmissive metasurface for different glucose concentration levels.
