Millimetre‐wave waveguide reflectometers for early detection of skin cancer

Millimetre‐wave (mm‐wave) reflectometry is an efficient technique for diagnosis of human tissue disease such as early stage skin cancer. Two sets of non‐invasive and in‐package reflectometers operating at 42 and 70 GHz are designed, fabricated and successfully tested with different kinds of samples. The tests are performed for a number of liquids, and pure water at different temperatures. Also, the proposed WR‐22 device is tested over skin at different locations. The clinical trial tests are performed on a number of volunteer patients who suffered from Basal cell carcinoma. The proposed devices are easy‐to‐fabricate, and provide a low‐cost solution for fast and accurate skin cancer detection. Furthermore, the proposed technology has the potential to be used for fast tissue inspection during a surgery
