Abstract We present a sensing system operating at millimetre (mm) waves in transmission mode that can measure glucose level changes based on the complex permittivity changes across the signal path. The permittivity of a sample can change significantl

Electromagnetic (EM) biomedical sensors in the mm-wave frequency range must detect small changes in signals in the presence of tissues, which are correlated to a pathological condition. These signals, however, can suffer from artifacts due to complex

Motion artifacts are a common source of noise in many commercial devices and measurement systems. They tend to adversely affect the information that is present in the signal of interest. These artifacts are often corrected using various postprocessin
