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).
