This note deals with some calculations involving the characteristics of the first normal modes and the lateral wave in a homogeneous straight dielectric slab bounded by free space on the one side and a perfect conductor on the other. Both the transmitter and receiver (isotropic radiators) are placed within the slab, d ( Km ) apart. The varying parameter is where k is the wave number, h is the width of the slab, and Δ n = n − 1 ≪ 1 is the deviation of the refractive index of the slab from the free space. The layer is, therefore, considered a “weak” one which makes the obtained numerical results applicable particularly to some types of low level just above the sea surface tropospheric waveguides supporting microwave propagation.
