We hybridized the rigorous coupled-wave approach (RCWA) with transformation optics to develop a hybrid coordinate-transform method for solving the time-harmonic Maxwell …
We present a modal method for the computation of eigenmodes of cylindrical structures with arbitrary cross sections. These modes are found as eigenvectors of a matrix eigenvalue …
Modern gyrotron beam tunnels are rather complicated structures designed to enhance the suppression of the parasitic oscillations, which may be excited there. In some beam tunnel …
A new method whose basis function expressed by that of a interface is proposed to analysis the grating diffraction, which can solve the physical defects of the Rayleigh method and …
The translational coordinate transformation method (the C method) in grating theory is studied numerically and analytically. We first study the convergence characteristics of the C …

We present an efficient Fourier modal method for wave scattering by perfectly conducting gratings (in the two polarizations). The method uses a geometrical transformation, similar to …
Waveguide-enhanced Raman spectroscopy (WERS) is becoming a promising emerging technology, and this work is aiming at three major problems that general WERS system are …
