Absorbedión

Absorbedión is a theoretical term used in material science and speculative physics to denote a property of a material or region that can absorb incoming energy with exceptionally high efficiency over a defined spectral range, while suppressing both reflection and transmission. The concept is closely related to the idea of a perfect absorber and is often explored within the framework of metamaterials and impedance matching.

In practical terms, absorbedión arises when the material's electric and magnetic responses are engineered to couple incident energy into internal degrees of freedom with minimal scattering. This is typically achieved through subwavelength structuring, resonant elements, and material losses tuned to the desired bandwidth and angle of incidence. The absorption coefficient A is defined as A = 1 − R − T, and absorbedión refers to situations where A approaches 1.

Research has demonstrated high-absorption devices in microwave, infrared, and terahertz regimes, with ongoing work aimed at broader bandwidth, angle invariance, and polarization independence. There are challenges: losses must be balanced with functional constraints, and fabrication can be complex.

In usage, absorbedión is discussed in theoretical discussions, experimental reports on metamaterial absorbers, and, more rarely, in science fiction contexts where it can underpin stealth, energy harvesting, or sensing narratives.
