    Abstract: A Fourier-Bessel equivalent of the plane wave technique is employed to theoretically analyze a circular photonic crystal structure containing both radial and rotational periodicity. The presence of the 12-fold rotational symmetry in the dielectric profile results in a 12-times reduction in the order of the matrix diagonalized when cast using the Fo... Show More

    Abstract: The dual laser wavelength Mach-Zehnder interferometric technique is used to study the thermal and optical properties of propylene carbonate (PC), which consider as important polar dielectric solvent for many laser dyes. Using Argon and He-Ne laser at wavelengths 514.5 and 632.8 nm as a light sources and Mach-Zehnder interferometer, many thermal and... Show More
