RISCircuit analysis and optimisation of SIW branch line coupler with improved modelling of small metallic post in FDTD
Year: 2017
Abstract:
In this study an improved model of small metallic post has been used in finite-difference time-domain (FDTD) method. This model has the advantages of wide range stability for different values of post radius, good accuracy and easy formulation...
