Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of surface plasmon polaritons even when bent, twisted or stretched. These ...

Food and drink makers have long been preparing for the UK’s incoming promotions ban on products high in fat, sugar or salt (HFSS). And now, it’s being ditched. Greenlight for junk food buy-one-get-one ...

Augmented reality (AR), the technology that overlays digital content onto what users see around them in real-time, is now widely used in the retail, gaming and entertainment industries, as well as in ...

Abstract: In this contribution, an Integral Equation (IE) formulation is proposed for the analysis of microwave circuits, based on the junction of two different rectangular waveguides coupled by an ...

How can you tell a food is palatable? New research uses three metrics – HFSS, UPF and HPF – to test whether palatability can be predicted. While different consumers like different foods, it can ...

Abstract: In this contribution, an electric field integral equation (EFIE) formulation is proposed, for the analysis of microwave circuits based on rectangular waveguides with an unlimited number of ...

Scientists announce the discovery of slab waveguides based on the two-dimensional material hexagonal boron nitride. The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State ...

One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites ...
