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 devices
• Includes several advanced simulation features for more efficient, fast band computations, such as inversion symmetry, mode seeding, and parity for 3D calculations
• Includes 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 systems
• Employs 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 maps
• Mode computation including Bloch and defect modes
• Wide range of measurements such as effective and group index, group velocity, and dispersion
• Equi-frequency plots for analysis of the entire Brillouin zone
• Light cone filters for photonic crystal slab applications
• Fixed-frequency analysis to incorporate material dispersion
