Abstract
Tomographycal methods of image reconstruction of two-dimensional objec ts, surfaces or subsurface regions in millimeter wavelengths band are suggested and considered. Experimental images obtained using antennas and waveguiding lines of different types and radiation frequency f app roximate to 33 divided by 35GHz are represented. Volumetric dielectric objects and plane-parallel ferrite (or dielectric) plates distributed in free space or in homogeneous dielectric medium have been taken as objects under investigation. It is shown that in the frequency band un der consideration, the images of investigated objects with characteris tic dimension A approximate to 2 lambda divided by lambda may be obtai ned by first-order diffraction tomography method (Born, Rytov or high frequency approximation of the first-order for electromagnetic field).
