Bandsolve

BandSOLVE Major Features Employs a very efficient and robust Plane Wave Expansion (PWE) algorithm that can solve for the band gaps of most 1D, 2D, and 3D PBG devicesIncludes several advanced simulation features for more efficient, fast band computations, such as inversion symmetry, mode seeding, and parity for 3D calculationsIncludes a Finite-Difference Time-Domain (FDTD) engine (for FullWAVE users only) for situations in which the PWE algorithm is not applicable, such as metallic and non-linear systemsEmploys complete and powerful post-processing tools for the calculation of a wide range of data and graphs. BandSOLVEs analysis features include: Band gaps, band maps, and gap mapsMode computation including Bloch and defect modesWide range of measurements such as effective and group index, group velocity, and dispersionEqui-frequency plots for analysis of the entire Brillouin zoneLight cone filters for photonic crystal slab applicationsFixed-frequency analysis to incorporate material dispersion
