A variational method is used to study the effects of addition of a low-index buffer layer over a high-index substrate on the propagation characteristics of a waveguide. For a buffered leaky waveguide with a single mode, the TM mode is more leaky out into the high-index substrate in comparison with the TE mode. Also, for a buffered leaky waveguide with three modes, the TE2 (TM2) mode is more leaky out and with a faster oscillation into the high-index substrate in comparison with the TE1 (TM1) and TE0 (TM0) modes..

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.
