In this communication a comprehensive study of the dielectric properties of human breast milk at microwave frequencies is reported. The samples are collected at weekly intervals following child birth. Measurements are made at the S -band of microwave frequency employing the rectangular cavity perturbation technique. The dielectric constants of the breast milk samples are found to increase as weeks elapse, which is attributed to the reduced fat content and increased lactose concentration. The conductivity of the breast milk samples is similarly found to increase due to the increased dilution.
