I have designed a 2-D planner photonic crystal, with Si rods in air background, offering photonic bandgap around 200THz. Using line defects, I have designed a coupled-resonator optical waveguide (CROW). Now, I want to find the effective refractive index of the entire system for each variation of defects' radii. I have used (...)
Hi, I was trying to find the modes of a symmetric photonic crystal based waveguide. The eigenmode solver of cst is doing nice with my requirement but in many publication people are getting even and odd modes within the band gap for a symmetrical structure. I am a bit confused that, do I have to do something to get both (...)
Hi, i am simulating a square lattice 2d photonic crystal and i want to get the dispersion diagram. For TE mode, i have periodic boundary at xy direction and electric boundary at z. An air box is placed above the substrate. phase x and y is scanned for the brillouin zone. The photonic crystal is a (...)
Hi Could anyone explain to me the concept and significance of mesh density as a function of steps per wavelength? I am asking this in context of a frequency domain EM-solver - cst MWS. May I ask what are the "steps" and what is the "wavelength" ? I am trying to simulate a photonic Crystal (silicon pillars in vacuum) (...)
The plane wave expansion method may be the most popular for calculating photonic band diagrams. Rigorous coupled-wave analysis and finite-difference time-domain may be the most popular for simulating scattering. With off-the-shelf software, you will find HFSS and cst very popular.
HI friends, Am new to use cst tool for simulation of optimizaion of bandgap in two dimentional can any one help me to how to work out this task and how results we can expect Thanks to everyone advancly for helping
Hi all i have determined the band structure of square lattice for Metallic PBG using cst and HFSS both. But i am not understanding hw i can determined the band structure for Triangular lattice for the same. what sould be unit cell type taken and how phase change is considered????? some (...)
Hi, As I am interested in mainly modeling diffractive/refractive structures or other similar optical devices, which package would be the easiest to learn/use and works well for optical device modeling? Thanks, ck1224

Hi who can guide me through simulating a published exapmle in cst at this address: I'de like to know the details of ports and boundary condition which have been used in time domain(transient solver). I will greatly appreciace whome helps me. regards
I want to simulate and extract some characteristics of a 2D photonic Crystal by cst 5.1. I used these settings for Units: THz, nsec, um Eigen Mode solver GaAs circular Disk 1-But I do not know how to extract Q factor of the structure? Can anyone help me about this issue? 2-Is cst 5.1 capable of doing Q (...)
All Dears, 1-For Analysing 2D photonic Crystals and obtaining their characteristics such as Transmission Spectra and photonic Band Gap(PBG), we should use Eigen Model Solver or Transient Solver (in cst software)? 2-what parameters should be noticed in simulation(I mean Boundary (...)
Could you please post your projet file? I have done quite a lot of eigenmode calculations for photonic crystals by using cst and also RSOFT Bandsolve.
PBG structure studying example of cst MWS. Enjoy it. Beware that in cst Microwave Studio, any photonic or electromagnetic band gap structures arranged in triangular unit-cell lattice will be model as an equivalent square lattice. In other words the natural symmetry points that the triangular lattice has will not be con
The energy balance correctly works only for closed structures. The radiation effects not takes into account. Only waveguide ports are considered. and quantum effects in photonic crystal not simulated by cst-MWS. If You simulate the photonic crystal based on classical EM-theory (quantum effects are not considered), the energy (...)
