SUMMARY

This discussion focuses on computing the resonance frequency of single cylinder scattering in photonic crystals using MATLAB. The user employs the expression J'(nkr)H(kr) - J(nkr)H'(kr) = 0, where J represents the Bessel function and H the Hankel function. However, the user encounters difficulties in achieving correct results with their MATLAB program. A suggestion is made to utilize COMSOL Multiphysics as an alternative tool for this computation.

PREREQUISITES
  • Understanding of photonic crystals and their properties
  • Familiarity with Bessel and Hankel functions
  • Proficiency in MATLAB programming
  • Knowledge of COMSOL Multiphysics software
NEXT STEPS
  • Explore MATLAB's capabilities for numerical solutions of differential equations
  • Learn how to implement Bessel and Hankel functions in MATLAB
  • Investigate COMSOL Multiphysics for simulating photonic crystal behavior
  • Study resonance frequency calculations in photonic structures
USEFUL FOR

Researchers in photonics, engineers working with optical materials, and anyone involved in computational modeling of photonic crystals.

Hi,
I research on photonic crystals.I want to compute resonance frequency for single cylinder scattering.
I use the below expression :

J'(nkr)H(kr)-J(nkr)H'(kr)=0

J:bessel and H:hankel function.

but I can't achieve correct result by write program in Matlab for computing that.

Can you help me ?

I think you should use the program "COMSOL Multiphusics".
