Discovery of topological LC circuits transporting EM waves without backscattering

In 2015, this research team successfully demonstrated topological properties in light and microwaves in a honeycomb lattice of dielectric cylinders, such as silicon. This time, the team revealed theoretically in a microstrip, a flat circuit, that electromagnetic waves attain topological properties when the metallic strips form a honeycomb pattern and the intra-hexagon and inter-hexagon strip widths are different. The team also fabricated microstrips and measured electric fields on their surfaces, and successfully observed the detailed structure of topological electromagnetic modes, where vortices of electromagnetic energy polarized in a specific direction are generated during the wave propagation.

This research demonstrates that topological propagation of electromagnetic waves can be induced using conventional materials in a simple structure. Because topological electromagnetic wave propagation is immune to backscatter even when pathways turn sharply, designs of compact electromagnetic circuits become possible, leading to miniaturization and high integration of electronics devices. In addition, the direction of vortex and the vorticity associated with topological electromagnetic modes may be used as data carriers in high-density information communications. All these features may contribute to the development of advanced information society represented by IoT and autonomous vehicles.

    Maybe you should at least RTFS? I know, no guarantee to find it informational at all times, but reading only TGT is almost guaranteed to let you less informed.

    As I said, I did RTFS. Maybe you should RTFPYRT.

    My point is that a headline should grab your attention and help understand why you should care about an article.

    IMO when editing an article, the editor should ALSO RTFS and make the headline useful. In this case, the title of the research paper makes a poor headline.

      True, but in these papers the object is to show off how educated you are. The rule is "never use a one syllable word when a four syllable will suffice." I once read a paper at work that had the word "enumerate" fifteen times in the first paragraph, without once using the word "count".

      Face it, with exceptions (e.g. Asimov) scientists can't write easily understood prose, or perhaps choose not to. I'd probably have had trouble with it if I knew any less about electricity.

        I agree, but I don't think the reason is to brag. I think it is to describe in precise and compact way. tbh it doesn't seem like it was the case for the enumerate paper you mentioned.

    Sisko: "What's happening out there?"
    Dax: "The team revealed theoretically in a microstrip, a flat circuit, that electromagnetic waves attain topological properties when the metallic strips form a honeycomb pattern and the intra-hexagon and inter-hexagon strip widths are different"
    Sisko: "Ahh, eletromagnatic waves topological honeycomb intra-hexagon."
    Dax: "Do you know what that is?"
    Sisko: "Just a guess here. Technobabble?"
