Finite Difference Time Domain (FDTD) based Modelling for Aerospace Applications

Finite Difference Time Domain (FDTD) based Modelling for Aerospace Applications

As mentioned above, the numerical methods such as MM-GSM, equivalent circuit, and TLTM methods are used for the analysis of FSS based radomes, RAS, and antennas. Apart from these methods, I have a very good experience of FDTD (finite difference time domain) based modeling in electromagnetics such as EM scattering, antennas, and FSS etc. Recently, the EM analysis of field distribution inside a hybrid-cylindrical microwave autoclave is carried out using 3D FDTD method.

 

Specifications

  • This method efficiently computes EM field in inhomogeneous and complex media
  • Capable of computing field distribution inside closed cavity 
  • Radar cross section of electrically small aerospace structures/ components
  • EM analysis of antennas

 

Major milestones / results of this technique:

 

Hybrid Cylindrical Microwave Autoclave developed at CSIR-NAL

 

  

EM field distribution inside hybrid cylindrical microwave autoclave in xy- and yz-plane
