According to enquiry-based learning theory and experiences in teaching Electric Circuits course, this paper presents a problem-based teaching model designed for transient response of dynamic circuits. Guided by some questions designed by teachers, students go through three processes: enquiry-based teaching and learning, problembased simulation, and enquiry-based seminar. The knowledge of dynamic circuits is taught, and the circumstance of scientific enquiry is also set up to help students' research. It is proved that the model can help students to understand knowledge much better, and it can also develop their ability of self-exploration.
A TE/TM wave splitter based on biaxial anisotropic slab is designed. According to the total reflection and total transmission of TE/TM waves incident from isotropic medium into biaxial anisotropic medium, we propose a wave splitter with simple structure and little limitation on both constitutive parameters and incident angle. All the results are verified by simulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
