multifeixe

Multifeixe is a term used in Portuguese to describe systems or concepts that involve multiple beams. It is not a formal, universally defined term in any single field, but rather a descriptive label that appears in technical discussions, translations, and some fictional or design contexts. Because it lacks a standardized definition, its precise meaning can vary depending on the discipline and author.

Etymology and usage

The word combines multi- (many) with feixe (beam). In practice, multifeixe is employed as an umbrella expression to indicate the presence or generation of several beams simultaneously, rather than a single cohesive beam. It may be used in optical, radio, or multimedia discussions, often alongside more specific terms such as multi-beam optical system or multibeam antenna, to convey the general idea of parallel or composite beam structures.

In optics

When applied to optics, multifeixe commonly refers to arrangements that produce or manipulate multiple light beams in parallel. This can occur through beam-splitting networks, diffractive optical elements, or multiplexed emission in laser and imaging systems. The concept is related to, but broader than, established ideas like beam forming and beam shaping.

In telecommunications and sensing

In radio and communications, multifeixe can describe antenna or transceiver configurations designed to form several directional beams for coverage, capacity, or tracking purposes. The established term in many technical contexts is multibeam or beamforming, with multifeixe serving as a language-specific or informal equivalent.

In fiction and design discourse

In speculative or design-oriented writing, multifeixe often denotes technologically advanced systems capable of generating or directing multiple beams for purposes such as scanning, targeting, or illumination.
