Abstract
Objective: The potentialities of improving the penetration of millimeter waves for breast cancer imaging are here explored. Methods: A field focusing technique based on a convex optimization method is proposed, capable of increasing the field level inside a breast-emulating stratification. Results: The theoretical results are numerically validated via the design and simulation of two circularly polarized antennas. The experimental validation of the designed antennas, using tissue-mimicking phantoms, is provided, being in good agreement with the theoretical predictions. Conclusion: The possibility of focusing, within a lossy medium, the electromagnetic power at millimeter wave frequencies is demonstrated. Significance: Field focusing can be a key for using millimeter waves for breast cancer detection
