In this study we propose and analyze a new paradigm of a dielectric relaxation spectroscopy (DRS) that operates at low frequencies (≤10 MHz) to measure polarization-lag of dielectric signals in breast capacitance when excited by pulses. As a result, the sensitivity of new DRS in detecting permittivity of water can increase by ≥80 times as comparing to conventional DRS operated at frequencies of 4GHz. This new system has advantages in enhancing repeatability between various readings, providing temperature-insensitive detection, and yielding higher sensitivity so as to, non-invasively, detect breast abnormalities that may lead to development of cancer in the near-term.
