Summary
This study introduces a flexible ultrawideband metamaterial absorber (MMA) using rubber and split square rings. The novel design achieves high absorptivity across a wide frequency range with multiple distinct absorption peaks.
Area of Science:
- Electromagnetics
- Materials Science
- Nanotechnology
Background:
- Metamaterial absorbers (MMAs) are crucial for electromagnetic wave manipulation.
- Achieving broadband absorption with multiple peaks in flexible MMAs remains a challenge.
Purpose of the Study:
- To propose and investigate a flexible ultrawideband metamaterial absorber (MMA).
- To achieve multiple perfect absorption peaks using a novel design.
Main Methods:
- Utilizing rubber as a flexible dielectric layer.
- Employing a split square ring resonator for metamaterial design.
- Simulating absorber performance using electromagnetic simulation software.
Main Results:
- A three-layer MMA demonstrated 90% absorptivity from 3.87 to 10.84 GHz.
- A five-layer MMA achieved 90% absorptivity from 3.78 to 9.85 GHz.
- The five-layer MMA exhibited peak absorptions of 99.99% to 100% at specific frequencies (4, 5.82, 8.46, 9.71 GHz).
Conclusions:
- The proposed flexible MMA effectively achieves ultrawideband absorption with multiple perfect absorption peaks.
- The design demonstrates potential for applications requiring flexible and efficient electromagnetic wave absorption.

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
1.8K
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

When protons A and X are coupled, their nuclear spin energy levels are slightly modified. This is because the energy required to excite proton A to a spin state parallel to proton X is slightly different from the energy required for it to become anti-parallel to spin X. Consequently, there are two possible excitation frequencies for A (A1 and A2), depending on the spin state of X, and vice versa. The mutual nature of coupling implies that the difference between frequencies A1 and A2, indicated...

5.1K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

If in an experiment, data values have a probability of being both positive and negative, neither the arithmetic mean, the geometric mean, nor the harmonic mean can be used to calculate the central tendency of the data set. In particular, if the positive and negative values are equally likely, the arithmetic mean is close to zero.
For example, consider the velocity of gas molecules in a container. The gas molecules are moving in different directions, which might impart positive and negative...
