How does FDTD work?
How does FDTD work and what problem does it solve? The FDTD method solves Maxwell’s equations on a mesh and computes E and H at grid points spaced Δx, Δy, and Δz apart, with E and H interlaced in all three spatial dimensions. FDTD includes the effects of scattering, transmission, reflection, absorption, etc.
What is the difference between FEM and FDTD?
FDTD is for time varying field and FEM is for harmonic field (time is frozen). FDTD is rather for CEM for example. FEM work well for antennas. About computer memory, the two simulations are volumic meshes so need huge memory (depend on the structure simulated).
What is FDTD lumerical?
Lumerical FDTD is the gold-standard for modeling nanophotonic devices, processes and materials. This finely tuned implementation of the FDTD method delivers reliable, powerful and scalable solver performance over a broad spectrum of applications.
What is Yee cell?
Finite-difference time-domain (FDTD) or Yee’s method (named after the Chinese American applied mathematician Kane S. Yee, born 1934) is a numerical analysis technique used for modeling computational electrodynamics (finding approximate solutions to the associated system of differential equations).
What is lumerical mode?
Lumerical MODE lets you focus on ideas and product, instead of worrying about how the software can get you there. The Bidirectional Eigenmode expansion and varFDTD engines easily handle both large planar structures and long propagation lengths, providing accurate spatial field, modal frequency, and overlap analysis.
What is finite integration method?
The Finite Integration Technique (FIT) is a consistent formulation for the discrete representation of Maxwell’s equations on spatial grids. First proposed by Weiland [1] in 1977, the finite integration technique can be viewed as a generalization of the FDTD method. It is also similar to the finite element method.
Why do we need to use numerical methods in electromagnetics?
Numerical methods exploit the blinding speed of modern digital computers to perform calcu- lations, and hence to solve large system of equations. These equations are partial differential equations or integral equations.
