Summary
We explored twisted split-ring resonator (SRR) pairs for terahertz (THz) applications. Integrating a ground plane enhances coupling, enabling control over resonance splitting and cross-polarization conversion for THz devices.
Area of Science:
- Metamaterials
- Terahertz (THz) Photonics
- Plasmonics
Background:
- Split-ring resonators (SRRs) are fundamental metamaterial building blocks.
- Edge-coupling of resonator pairs influences electromagnetic response.
- Terahertz (THz) frequencies offer unique applications in spectroscopy and sensing.
Purpose of the Study:
- Investigate edge-coupling of twisted split-ring resonator (SRR) pairs in the terahertz (THz) range.
- Analyze resonance splitting and cross-polarization conversion phenomena.
- Explore the impact of a metal ground plane on system performance.
Main Methods:
- Theoretical modeling using a coupled-resonator model.
- Numerical simulations of electromagnetic response.
- Experimental verification of theoretical predictions.
Main Results:
- Observed resonance splitting and cross-polarization conversion in twisted SRR pairs.
- Demonstrated resonance splitting dependence on coupling strength (SRR separation).
- Showcased significant enhancement of resonance coupling and control via a metal ground plane.
Conclusions:

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

2.0K
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.

2.8K
The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling.
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene...

In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.

According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, the actual distribution of electrons is an average of that shown by the various Lewis structures.

The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:
