The book "Design of Microstrip to Substrate Integrated Waveguide Transition" by Farouk Grine offers a comprehensive analysis of Substrate Integrated Waveguide (SIW) technology. This technology represents a significant advancement as it enables the transition from traditional metal walls to a planarized structure. The book addresses the integration of microstrip lines into SIW, which poses a challenge due to the geometric incompatibility of these two structures. To overcome this challenge, various transitions, connections, and couplings are developed that require high technical quality. Precise calculation and modeling of these transitions are crucial to ensure optimal impedance matching and field alignment between SIW and planarized circuits. This specialized book is aimed at professionals and students involved in the development and application of SIW technologies.
