The variational method is applied to determine the propagation eigenmodes in a waveguide where a lossless glass substrate has refractive index lower than that of the lossy superconducting guiding layers. For this waveguide, the TM mode is more confined within the core layer and in superconducting thin films and more evanescent in the air claddings in comparison with the TE mode. The maximum for the imaginary part of the effective index and the maximum of the fractional power guided in superconducting layers for TM mode are smaller and shifted to higher values of the glass thickness in comparison with the TE mode.

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.
