Distances in Higher-Order Networks and the Metric Structure of Hypergraphs.

We explore the metric structure of networks with higher-order interactions and introduce a novel definition of distance for hypergraphs that extends the classic methods reported in the literature. The new metric incorporates two critical factors: (1) the inter-node distance within each hyperedge, and (2) the distance between hyperedges in the network. As such, it involves the computation of distances in a weighted line graph of the hypergraph.

Suppressed light transmission through corrugated metal films at normal incidence.

In the study of light transmission through corrugated metallic film, it has been shown that along with the enhancement of light transmission, suppression may take place at specific values of the period and magnitude of corrugation for normal light incidence. Suppression was found to be due to the interplay between symmetric and assymetric surface plasmon polariton modes at their simultaneous excitation.
