Abstract-This paper presents a novel method for microwave breast cancer detection using a parallel-plate waveguide probe. The method is based on detecting the dielectric contrast between a malignant tumor and its surrounding tissues. Our analysis and simulations indicate that scattered signals from a tumor (modelled as a lossy dielectric sphere with higher dielectric constant than the surrounding tissues) received in the form of S parameter S 11 have resonating characteristics in the frequency range of 1 to 7 GHz. A frequency scan of the resonant scattered signals provides data of the presence and location of the tumor. Through numerical examples, the effectiveness of the proposed methodology to detect breast tumors of different sizes, embedded at different depths and to distinguish a tumor from clutter items is demonstrated.

“…The way of research on radar cross section (RCS) includes calculation and measurement [1][2][3][4][5][6]. Though the theory of electromagnetism is integrated which can analyze many typical targets scattering mechanism, it's hard to calculate the targets which have complex structure and compound materials.…”

Abstract-Based on the step-frequency RCS measurement system, high performance absorbers and low scattering supports, employing two log-periodic dipole antennas to carry out the quasi-monostatic measurement and many DSP techniques to reduce the error, the indoor accurate RCS measurement can be completed on UHF band. Experimental results show that the valid data waved less than 1 dB can be obtained over 70% of whole band.

Abstract-The scattering of visible light by hexagonal-shaped column containing densely packed inclusions is simulated by a combination of ray-tracing and Monte Carlo techniques. While the ray tracing program takes care of the individual reflection and refraction events at the outer boundary of the particle, the Monte Carlo routine simulates internal scattering processes. A dense-medium light-scattering theory based on the introduction of the static structure factor is used to calculate the phase function for densely packed inclusions. Numerical results of the phase function for a randomly oriented hexagonal-shaped ice crystal with multiple densely packed inclusions are evaluated.
