Wireless sensors embedded in high permittivity lossy media
, 2023 The design of wireless sensors for operation embedded in a medium with high losses creates a series of additional constraints that should be taken into consideration at design stage to enhance sensor performance. In such a medium, both the real and the imaginary part of the relative permittivity will have a high value. In this thesis, the effect of the
