The study on the MATLAB based design, simulation & corresponding analysis of Microwave Microstrip Low-Pass Filter (Butterworth & Chebyshev) System Parameters by Insertion Loss Method proposes the practical solution for overcoming the tedious job of detail calculation & corresponding rigorous analysis of several System Parameter values associated with the design, testing & troubleshooting of Microstrip LPF by Insertion Loss Method. It has evolved from the academic projects carried out by the authors over many years. The book uses recent advances in research for update presentation of the design & analysis using MATLAB with the potential for future developments. To facilitate readers understanding, lucid form of presentation is given depending on related real-world applications & modern computing tool - MATLAB, that is extensively used in Electromagnetics. Readers will find this book as easy to comprehend in design, analysis, detail in-depth explanation & extensive references of Microstrip LPF using MATLAB simulated results.
