Asymmetric coupling and dispersion of surface-plasmon-polariton waves on a periodically patterned anisotropic metal film
Jhuma Dutta, S. Anantha Ramakrishna, Akhlesh Lakhtakia
The morphology of a columnar thin film (CTF) of silver renders it an effectively biaxially anisotropic continuum. CTFs of silver deposited on one-dimensional gratings of photoresis…

Periodically patterned columnar thin films as Blazed gratings
Jhuma Dutta, S. Anantha Ramakrishna, Akhlesh Lakhtakia
Periodically patterned columnar thin films (PP-CTFs) were made by evaporating CaF2 and directing the vapor flux obliquely towards lithographically fabricated micrometer/sub-microme…
