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
