Alzheimer’s disease (AD) is the most common form of dementia, affecting millions of people worldwide and posing increasing challenges to healthcare systems. Early, noninvasive diagnosis is a paramount medical need. This thesis contributes to exploring the feasibility of Microwave imaging (MWI) as a possible solution. When exposed to microwaves operating at about 1 GHz, the scattering response of healthy and AD-affected tissues alters due to dielectric contrast arising from physiological changes in the Cerebrospinal fluid (CSF), a tissue that supports and protects the central nervous system. By conducting a preliminary numerical analysis, the performance of an MWI setup in various pathological scenarios that gradually worsen has been estimated.
