Modern satellites rely on electromagnetic waveguides—hollow structures that carry high-power signals between components such ...

"Because the most common electromagnetic waveguides are rectangular-shaped, our origami designs needed to maintain a rectangular cross section in the operational state for comparable performance." ...

The drive to shrink advanced electro-optical medical instrumentation on-chip and in-chip continues along diverse paths. For example, optical coherence tomography (OCT) is a relatively new but now ...

Abstract: In this article, an improvement of the Nicolson-Ross-Weir (NRW) transmission/reflection method based on the rectangular waveguide is proposed, providing a ...

Abstract: In this article, the comprehensive general synthesis theory and design method for unequal filtering rat-race coupler (FRC) terminated complex impedances is presented, and the hardware is ...
