abstract

  • Biosensing is a technique used to examine an individual’s internal anatomy without the need for invasive surgery. There are many modalities used for biosensing, but the unifying factor for each is their ability to differentiate between abnormal and healthy tissue through differences in the tissue’s material properties. Among them, biosensing through the propagation of electromagnetic waves in the radiofrequency (RF) and microwave spectral regions has proven to be more effective due to its unique properties. The most ideal way to test microwave systems for biosensing is through excised tissue, however, there are health and ethical concerns related to obtaining excised tissue. As a result, tissue mimicking materials, which are also known as tissue phantoms, are a necessary tool that can be used to test microwave propagation through biological tissue. Tissue phantoms are inorganic materials that replicate the properties of biological tissue. According to the article, (S. Castello-Palacios, C. Garcia-Pardo, M. Alloza-Pascual, A. Fornes-Leal, N. Cardona and A. Valles-Lluch, "Gel Phantoms for Body Microwave Propagation in the (2 to 26.5) GHz Frequency Band," IEEE Transactions on Atennas and Propagation, pp. 1-10, 2019), not only do they aid in providing the desired electrical properties of the tissue, but they also help better understand the propagation of RF and microwave signals under different excitations and operating conditions.
