near-field coupling

[/nɪr fild ˈkʌplɪŋ/]
nounpl: near-field couplings
acoplamento de campo próximo
1. A phenomenon in electromagnetism where energy is transferred between two devices through the near-field region (within one wavelength of the source), without radiating electromagnetic waves into the far field
Near-field coupling is used in wireless charging systems to transfer power efficiently between a transmitter coil and a receiver coil.
O acoplamento de campo próximo é utilizado em sistemas de carregamento sem fio para transferir energia de forma eficiente entre uma bobina transmissora e uma bobina receptora.
2. The electromagnetic interaction that occurs at close distances where the electric and magnetic fields are not in phase, typically used in inductive or capacitive coupling applications
Near-field coupling enables the operation of RFID tags at short distances without direct electrical contact.
O acoplamento de campo próximo permite o funcionamento de etiquetas RFID em distâncias curtas sem contato elétrico direto.
This is a specialized technical term primarily used in electronics, telecommunications, and physics communities in both Brazil and the United States. It has gained prominence in recent years due to increased adoption of wireless charging technology and near-field communication (NFC) in consumer devices. The term is consistently used across both Portuguese-speaking and English-speaking technical communities without significant variation.
