Abstract
The cylindrical wave approach is resumed. It is a full-wave technique for the solution of the two-dimensional plane-wave scattering problem by a set of perfectly conducting and dielectric cylinders buried in a dielectric half-space, or in a finite-thickness slab. This method can be applied for simulating scenarios with cylindrical inhomogeneities buried in the earth. New numerical results are presented, concerning the simulation of buried utilities. In particular, metallic pipes and air cavities are simulated.

Our work on the development of the cylindrical-wave approach for the solution of the twodimensional plane wave scattering problem by a set of perfectly conducting and dielectric cylinders buried in a dielectric half-space or in a finite-thickness slab, is shortly reviewed
Summary
The Ground Penetrating Radar (GPR) [1, 2] is an established and routine method for the inspection of civil engineering structures. The cylindrical-wave approach (CWA) [11,12,13, 22, 23] is an efficient spectral-domain technique, developed for the rigorous solution of the two-dimensional electromagnetic forward-scattering problem by a finite set of perfectly conducting or dielectric targets, buried in a dielectric halfspace or in a finite-thickness slab. In this method, the field scattered by underground objects is represented in terms of a superposition of cylindrical waves. An electromagnetic simulation is performed of suitable scenarios in the context of civil engineering applications
