Inverse Design of SIW Devices Based on the Internal Multiport Method
IEEE MICROWAVE AND WIRELESS TECHNOLOGY LETTERS(2024)
摘要
This letter presents a novel inverse design method for substrate-integrated waveguide (SIW) devices. Based on the internal multiport method (IMPM), the metallic via arrangement in the SIW structure is converted to a numerical optimization problem on a binary-option vector. By simply inputting the expected device performance, a satisfying via implementation can be automatically generated aided by the numerical optimizer, without sophisticated structural analysis and repeated full-wave simulation. Application examples are shown to verify the effectiveness and efficiency of the proposed method.
