Pasian, M. Zhadobov, M. Pouliguen, P. Potier, P. Perregrini, L. Sauleau, R. Ettorre, M. Publication year 2021 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 Subject Breast cancerMicrowave imagingMillimeter wavesRadial line slot arraysNear-field optimization To reference this document use: http://resolver.tudelft.nl/uuid:c7829685-be30-404c-b1c0-245c6ef7b21b TNO identifier 957512 ISSN 0018-9294 Source IEEE Transactions on Biomedical Engineering, 68 (68) Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
