Measurements of the propagation of UHF radio wa¨es in two trapezoidal tunnels are reported. Values of propagation loss in dBr100 m are gi¨en. It is found that the propagation attenuates at least 900 MHz. In addition, a portable FM radio system operating at 900 MHz is tested in one tunnel. It achie¨e

The solenoidal basis functions defined on tetrahedrons are modified to permit the analysis of the problem of scattering of electromagnetic wa¨es by inhomogeneous dielectric objects. In the analysis of the scattering of EM plane wa¨es by an inhomogeneous dielectric cube, we compare our results with t
