Cooperative Allosteric Transitions01:58

Cooperative Allosteric Transitions

8.7K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Cooperative Binding of Transcription Regulators

7.3K
Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form...

Chirality02:25

Chirality

29.4K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Group Polarization01:01

Group Polarization

39.2K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Area of Science:

  • Metamaterials and Nanophotonics
  • Electromagnetic Metasurfaces
  • Applied Physics

Background:

  • Next-generation communication and camouflage systems demand secure information transmission with minimal electromagnetic (EM) exposure.
  • Existing radiation-stealth metasurfaces struggle with intrinsic entanglement of radiation and scattering, limiting polarization control and spectral coexistence.
  • Current methods segregate radiation and scattering into orthogonal polarizations or disjoint frequency bands, hindering concurrent full-polarization stealth and radiation control.

Purpose of the Study:

  • To propose and demonstrate a novel multigroup metasurface ensemble that decouples radiation regulation from scattering suppression.
  • To achieve dynamic chiral radiation and full-polarization invisibility across an overlapping spectrum.
  • To overcome the limitations of existing metasurfaces in polarization controllability and spectral coexistence.

Main Methods:

  • Utilizing cooperative interlayer interactions within multigroup metasurface ensembles.
  • Leveraging two independent geometric phases to break the conjugation constraint between radiated and scattered spin waves.
  • Implementing a customized feed-addressing strategy to control radiation direction and suppress cross-polarized scattering via destructive interference.
  • Ensuring co-polarized illumination is dissipated by an embedded feed network for full-polarization invisibility.

Main Results:

  • Demonstrated full decoupling of radiation regulation from scattering suppression.
  • Achieved dynamic chiral radiation with tunable beam scanning.
  • Experimentally validated full-polarization invisibility across an overlapping spectrum.
  • Showcased suppression of cross-polarized scattering through destructive interference.

Conclusions:

  • The proposed multigroup metasurface ensembles enable unprecedented control over radiation and scattering.
  • This methodology provides a versatile foundation for secure satellite links, low-altitude networks, and covert tactical communications.
  • The achieved dynamic chiral radiation and full-polarization invisibility unlock new possibilities for next-generation aerospace and wireless infrastructures.
