EMBox Lab

The Anyfields technology is an antenna measurement solution based on infrared thermography. Each system integrates four core components: a mini anechoic chamber that ensures a clean and controlled electromagnetic environment for the measurement, an absorbing film onto which the antenna radiates, a high-resolution infrared camera that captures the resulting thermal image, and a dedicated software suite that transforms the raw thermal images into quantitative, exploitable measurement data. Powered by advanced signal processing algorithms, this software converts the captured images into calibrated electric field maps and extracts key RF performance parameters such as gain, radiation patterns or HPBW. Together, these elements deliver a complete, self-contained measurement setup.

When the antenna under test radiates onto the absorbing film, the electromagnetic energy is converted into heat, causing the film to warm up locally according to the antenna’s radiation pattern. The infrared camera then captures a high-definition thermal image of the film, where each pixel corresponds to an individual measurement point, delivering up to 300,000 data points in a single shot. Advanced data processing algorithms then convert this thermal image into a calibrated electric field map, providing instant visual diagnostics of the antenna’s radiation behavior.

Yes. The Anyfields technology was developed from over 20 years of research conducted at ONERA, the French Aerospace Lab, one of France’s leading public research institutions. It is protected by multiple patents, originally filed by ONERA and exclusively licensed to Anyfields, with additional proprietary patents filed by the company itself. This multi-patented foundation reflects the depth of the scientific and engineering work behind the technology.

The EMBox Lab is an educational antenna measurement tool. It measure antennas to obtain visual E-Field maps of antenna radiation, making electromagnetic phenomena and RF concepts directly observable — helping students move from abstract theory to tangible, real-world understanding.

The EMBox Lab is an educational demonstration tool designed for teachers, researchers, and their students. It is adapted for both interactive lectures and practical lab sessions. For first-year students, it provides a clear visual understanding of radiation and field behavior. Advanced students can use it to characterize antennas, visualize hot spots through mapping, and measure key parameters such as gain, radiation patterns, and reflection coefficients.

The EMBox Lab is based on the Anyfields Technology based on the infrared thermography, enabling one click measurement and high-definition visualization of antenna radiation with a single click for instant performance diagnostics.

The software enables to export all measurement datasets in differents formats : csv, json, png. Export data format can be adapted to user needs if required. 

Traditional teaching methods, heavy on theory and light on practical application, often fail to resonate with students. Without practical demonstrations, abstract concepts like radiation, impedance, and wave propagation remain difficult to grasp. The EMBox Lab bridges this gap: by combining theoretical instruction with direct measurement and visualization, the tool is particularly relevant for courses related to radio frequencies and antennas. Its compact format, user-friendly interface, and quick setup make it suitable for live demos during lecture and also for integration into university laboratory sessions.

These are two very different tools using two different measurement approaches and technologies. A VNA measures S-parameters (such as S11 for return loss and S21 for transmission) at specific ports, it gives precise numerical data but no spatial visualization of the field. The EMBox Lab, by contrast, makes electromagnetic fields visible in high definition, capturing up to 300,000 measuring points in a single shot, providing a visual representation of how the antenna radiates. It is not a replacement for a VNA but a complementary tool focused on education, field visualization, and rapid diagnostics rather than precise parametric characterization.

The EMBox Lab served as a complete radiofrequency test and measurement setup during classroom sessions, enabling the visualisation of radiation patterns and electromagnetic behavior. The fast measurement process allowed several configurations to be analyzed within one class session, enabling students to easily compare antennas and observe differences in radiation behavior.  A starter pack including turnkey lab exercises and 3 antennas is included anyfields, making it easy to get started immediately.

Students can use the system to explore the radiation variation by changing the measurement distance or frequency, the behavior of electromagnetic fields when power is transmitted, the graphical representation of gain and HPBW, and the validation by comparing the measurement with a simulation. Measurable parameters include E Field values, gain, radiation patterns, reflection coefficients, and near-field/far-field distributions.

Simulations (using tools like CST, HFSS, or FEKO) are mathematical models of antenna behavior, they are fast and flexible but based on assumptions and idealized conditions. A measurement with the EMBox Lab captures the real physical behavior of an actual antenna. Students can design an antenna in simulation and then upload it with EMSoft to compare the results with real  ANYFIELDS measurements. These will indeed reveal manufacturing imperfections, environmental effects, and deviations from the theoretical model. Seeing the field establish in real time is a great add on to antenna simulation and greatly enhances comprehension anyfields in a way that no simulation alone can achieve.
