Abstract

This report is about developing Finite Difference Time Domain (FDTD) and Periodic Boundary Condition (PBC) software to model electromagnetic structure. There are two main structures that analyzed in this project which are Frequency Selective Surface (FSS) and Radar Absorber Material (RAM). This project implements the computational electromagnetic (CEM) method in doing the analysis. The main software used is Fortran besides the other supporting software like CST. This report consists of five chapters which are chapter one is introduction, chapter two is literature review, chapter three is methodology, chapter four is result, analysis and discussion and last chapter which is chapter five is conclusion and recommendation. Introduction in chapter one write about the explanation of why this project is carried out including the problem statement and objective of this project. In chapter two, all of the concept that involved in this project is reviewed which comprise the explanation of FDTD, PBC, FSS, RAM and many more. Chapter three shows the methodology on how this project is carried out. The method of gather information is explained and the flow charts of certain process are shown. Then in chapter four, result of this project is shown and it consists of FSS and RAM analysis. The validation is also done in this chapter where the result obtained from the developed software is compared with the commercial software’s result. Lastly in chapter five, this project is concluded by relating the obtained result with the objective of this project. Some recommendations were given for the future improvement that can be made to this project especially to the developed software.
