Frequency inversion method and device for malignant melanoma detection using RF/microwaves
Artikel i vetenskaplig tidskrift, 2024

The paper considers an inverse problem of reconstructing the spatially distributed complex dielectric permittivity function using backscattered data of the electric field in the frequency domain. We develop iterative algorithm for reconstruction of this function. Numerical example show the performance of the proposed algorithm in 2D. Additionally, we present at the first time the new prototype of device for the malignant melanoma detection which is modelled in HFSS/Ansys. Results of measurements of scattered parameters in HFSS/Ansys show significant phase distortion in the case when melanoma is present compared to the case when melanoma is absent.
