The phrase "absorption over a" is not complete and lacks context, making it difficult to determine its correctness in written English.
It could be used in contexts discussing the absorption of substances or energy over a specific area or time frame, but additional information is needed for clarity.
Example: "The study focused on the absorption over a defined surface area to measure the effectiveness of the new material."
Alternatives: "absorption across a" or "absorption within a".
I note that there is a correlation between radiation absorption over a lifetime and cancer rate.
The absorber exhibits near-unit absorption at multiple adjacent wavelengths overlapping with each other, which results in a high absorption over a wide wavelength range.
Results show that for this configuration, the active impedance load is responsible for the main part of the power absorption over a broad frequency range.
A nearly total absorption over a wide frequency band can be obtained for thin structures, even for frequencies below the quarter wavelength resonances i.e., in a sub-wavelength regime.
The waveguide characteristics of the honeycomb combined with the performance of the foam lead to unexpectedly large EM power absorption over a wide frequency range, superior to any known material.
To solve the EMI problem, the development of microwave-absorbing materials with strong absorption over a broad frequency range is required urgently.
When this idyll of self-absorption is over, a man (Brian Murray) walks onto the stage.
The pure phase PVSK film with 1.67 mol% PEA2PbI4 shows enhanced absorption over all wavelengths (Fig. 1c) compared to the bare FAPbI3 film where the absorption onset is hardly changed (Insent of Fig. 1c).
The proposed absorber can achieve a broadband absorption over 90% with a bandwidth of 4.8 Thz through altering the Fermi energy E f of different graphene layers.
Detailed kinetic studies of Ni, Cd, and Tl uptake by intact plants demonstrate multiphasic root absorption processes over a broad concentration range, and the use of transport mechanisms in place for the nutrient ions Cu, Zn, and K. Advantages and limitations of higher plants as indicators of increased levels of metal pollution are discussed in terms of these soil and plant phenomena.
With this design, devices with a very thin active layer can achieve near perfect absorption because of both efficient anti-reflection and absorption enhancement over a broadband of spectra and a wide range of angles of incidence.
