Özet
Inherent dielectric properties discrepancy between
different tissues have long been of interest to researchers in
order to improve medical diagnostic approaches and therapeutic
technologies. Hence, determination of the dielectric properties
for biological tissues is keystone to develop an innovative
medical system. Widely, the dielectric properties of biological
tissues have been determined by utilizing slim form open-ended
probes. Although, the method is superior to other dielectric
property measurement techniques in several aspects, the mea-
surement procedure suffers from equipment-related and tissue-
related errors. Sensing depth, which is one of the confounders
can be associated with both equipment- and tissue-related
errors. In this work, we performed the preparation of skin
mimicking phantom and conducted a series of experiments on
a two-layer configuration consisting of the prepared phantom
and a liquid (olive oil). Furthermore, the sensing depth of the
2.2mm aperture open-ended coaxial probe was analyzed at five
different frequencies. The results obtained show that the sensing
depth of biological tissues strongly depends on the operation
frequency. We also observed that the sensing depth decreases
at higher frequencies and this is a property can be utilized
in tackling thin multi-layered structures problem such as skin
cancer detection.
