The present study deals with synthesizing mixture solutions which can be used as muscle and adipose tissue mimics for applications in microwave medical imaging. Dielectric parameters were measured as a function of frequency for ultrawideband applications between 500 MHz and 50 GHz and mixtures utilizing concentrations of bovine serum albumin (BSA) in phosphate buffered saline (PBS) were synthesized with the aim of mimicking in vivo and ex vivo muscle tissues. Emulsions consisting of concentrations of peanut oil and Triton X-100 (TX) in PBS solutions were also synthesized to mimic in vivo and ex vivo adipose tissue. Results were compared to measured dielectric parameters of in vivo and ex vivo biological tissues from a previous study. Good agreement with experimental results was observed implying that our hypothesis was fulfilled. Such solutions might ultimately be utilised in the construction of human body phantoms for narrowband and ultra-wideband microwave devices.
