  2. Radiation pattern - Wikipedia

    en.wikipedia.org/wiki/Radiation_pattern

    In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source. [1][2][3] Particularly in the fields of fiber optics, lasers, and integrated optics, the term radiation pattern may also be used ...

  3. Associative interference - Wikipedia

    en.wikipedia.org/wiki/Associative_interference

    Diagram explaining how associative interference is caused. Associative interference is a cognitive theory established on the concept of associative learning, which suggests that the brain links related elements. When one element is stimulated, its associates can also be activated. [1] The most known study demonstrating the credibility of this ...

  4. Adaptive beamformer - Wikipedia

    en.wikipedia.org/wiki/Adaptive_beamformer

    The adaptive beamforming system dynamically adapts in order to maximize or minimize a desired parameter, such as Signal-to-interference-plus-noise ratio. An antenna gain pattern created by adjusting phase and magnitude of signal transmitted by Tx1, Tx2, and Tx3. Dynamically adjusting phase and magnitude will cause the antenna gain pattern to ...

  5. Holonomic brain theory - Wikipedia

    en.wikipedia.org/wiki/Holonomic_brain_theory

    Holonomic brain theory is a branch of neuroscience investigating the idea that human consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [1] Holonomic brain theory is opposed [citation needed] by traditional ...

  6. Antenna diversity - Wikipedia

    en.wikipedia.org/wiki/Antenna_diversity

    Antenna diversity is especially effective at mitigating these multipath situations. This is because multiple antennas offer a receiver several observations of the same signal. Each antenna will experience a different interference environment. Thus, if one antenna is experiencing a deep fade, it is likely that another has a sufficient signal ...

  7. Grating lobes - Wikipedia

    en.wikipedia.org/wiki/Grating_lobes

    A typical radiation pattern of phased arrays whose inter-element spacing is greater than half a wavelength, hence the radiation pattern has grating lobes.. For discrete aperture antennas (such as phased arrays) in which the element spacing is greater than a half wavelength, a spatial aliasing effect allows plane waves incident to the array from visible angles other than the desired direction ...

  8. Moiré pattern - Wikipedia

    en.wikipedia.org/wiki/Moiré_pattern

    In mathematics, physics, and art, moiré patterns (UK: / ˈ m w ɑː r eɪ / MWAH-ray, US: / m w ɑː ˈ r eɪ / mwah-RAY, [1] French: ⓘ) or moiré fringes [2] are large-scale interference patterns that can be produced when a partially opaque ruled pattern with transparent gaps is overlaid on another similar pattern. For the moiré ...

  9. Wave interference - Wikipedia

    en.wikipedia.org/wiki/Wave_interference

    In physics, interference is a phenomenon in which two coherent waves are combined by adding their intensities or displacements with due consideration for their phase difference. The resultant wave may have greater intensity (constructive interference) or lower amplitude (destructive interference) if the two waves are in phase or out of phase ...
