Polypropylene-substrate-based SRR- and CSRR- metasurfaces for submillimeter waves

Optics Express, 2008
In this paper it is presented the fabrication of low loss millimeter wave metamaterials based on patterning on polypropylene substrates by conventional contact photolitography. We study numerically and experimentally the transmission and reflection properties of two dimensional arrays of split ring resonators (SRRs), or metasurfaces, and their ...

Processing and release of endogenous immunogenic peptide signals

The Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY In both animals and plants, small secreted peptides known as cytokines and phytocytokines mediate local and systemic communication during immune and stress responses. These signaling molecules are typically synthesized as inactive precursors that require proteolytic processing to become active.
