The far - field characteristics of line sources lying between the slabs of a multi - dielectric substrate configuration are presented. Such a configuration is usual in the technology of microstrips as well as in remote sensing. The electric field is expressed in the form of a Fourier integral of the potential V(y,h), which is given by the solution of the 2-D wave equation. The unknown coefficients of the solution are found from the boundary conditions of the electric and magnetic fields at the interfaces of the substrates. A set of numerical results for one to many substrates media give interesting radiation patterns. The main conclusion is that the patterns from a line source are similar to that given in free space by a complex array of sources. Symmetric or non - symmetric configurations give patterns with the corresponding characteristics. The ray optical techniques fail for more than three substrates, due to multi - reflection and refraction, while our procedure can be applied for any set of lossless or lossy substrates.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
