Development Of Breast Phantoms For Ultra-wideband (Uwb) Microwave Imaging Systems

Ultra-wideband (UWB) microwave imaging is a promising new alternative technology for detecting breast cancer tumours in the early stages. However, the calibration kit is required in this study to obtain accurate results. Therefore, breast phantoms with properties similar to biological breast tissues...
