Electromagnetic Field Confinement for Wireless Power Transfer
OMNIWAVE is a wireless power transfer technology developed by GRADCOM based on electromagnetic field confinement and controlled near-field energy extraction.
The technology aims to enable efficient wireless energy delivery without relying on conventional inductive pads, radiative antennas or strongly localized charging points. Instead, OMNIWAVE uses engineered electromagnetic structures to guide and confine energy, creating controlled near-field regions from which power can be extracted efficiently and safely.
OMNIWAVE represents a natural evolution of GRADCOM’s previous work on RFID, near-field systems, antennas, microwave engineering and electromagnetic field-confinement devices.

Technology Concept
OMNIWAVE is based on specially designed electromagnetic guiding structures capable of transporting energy while keeping the electromagnetic field confined around the device.
A receiver placed within the confined field region can extract part of the guided energy through near-field coupling. This approach opens the way to wireless power transfer systems in which energy is not emitted freely into space, but remains localized and available along a controlled propagation path.
The concept is particularly attractive for applications where conventional wireless power transfer solutions face limitations due to alignment constraints, radiation losses, safety concerns, reduced flexibility or limited scalability.
Key Features
Field-Confining Energy Transport
OMNIWAVE is designed to guide electromagnetic energy while minimizing unwanted radiation. This allows power to be transported and accessed through a confined near-field region.
Controlled Energy Extraction
Receivers can be designed to extract energy from the confined field without requiring direct electrical contact with the emitter structure.
Reduced Radiation Losses
Unlike radiative wireless power transfer systems, OMNIWAVE is based on non-radiative or weakly radiating near-field mechanisms, reducing the amount of energy lost into free space.
Scalable Architecture
The guiding structure can be adapted to different geometries, power levels and application scenarios, from compact demonstrators to larger-scale energy-transfer platforms.
Industrial Integration Potential
The technology can be integrated into engineered surfaces, platforms, infrastructures or dedicated devices where localized wireless power delivery is required.
Potential Applications
OMNIWAVE technology can be explored in several application domains, including:
- Dynamic wireless power transfer
- Wireless charging of mobile platforms
- Energy delivery to autonomous systems
- Industrial wireless power transfer
- Contactless power delivery in controlled environments
- Smart infrastructures
- Wireless energy distribution along guided paths
- Electromagnetic field-confinement devices
- Secure and localized wireless powering systems
From RFID to Wireless Power Transfer
OMNIWAVE builds on GRADCOM’s experience in near-field RFID systems, electromagnetic field confinement, metamaterial-inspired structures, antennas and microwave engineering.
The same fundamental idea that enables the localization of electromagnetic fields for reliable identification can be extended towards controlled wireless energy transfer.
This evolution connects several of the group’s core research lines:
- Near-field RFID
- Electromagnetic field confinement
- Guided-wave structures
- Microwave engineering
- Antenna and coupling systems
- Wireless power transfer
OMNIWAVE represents a step forward in the development of electromagnetic technologies that control not only how information is transmitted, but also how energy can be guided, confined and extracted.
Development Status
OMNIWAVE is currently being developed as a proof-of-concept technology within the UAB Proof of Concept Programme.
