Reconstruction of Three Dimensional Inhomogeneous Bodies Using Unrelated Illumination

Abstract--The unrelated illumination method is used to estimate the complex permittivities of three-dimensional inhomogeneous dielectric bodies. Starting from the integral representation of the electric field and using the method of moments, the object under investigation is illuminated by a group of unrelated incident fields. Computer simulations show that the method can be used to overcome the severe ill-posedness of the three-dimensional problem even in the presence of noise and with the use of only one detector to measure the external scattered field.
