Intelligent Electromagnetic Sensor Laboratories
The iEMSL offers precise 2D and 3D radiation pattern measurements to characterize antennas and devices across a broad spectrum of frequencies, from 400MHz to mm-Wave, ensuring accurate performance evaluation for cutting edge-applications.The Intelligent Electromagnetic Sensor Labs (iEMSL) at Texas A&M University is a newly renovated, state-of-the-art electromagnetics facility located in the Wisenbaker Engineering Building. Spanning 4,600 sq ft, the iEMSL offers the Texas A&M community and external partners advanced electronic measurement capabilities, covering DC to millimeter-wave frequencies. The facility supports antenna and device/material characterization, signal generation and analysis, and system-level testing for communications, radar, and other wireless applications. Additionally, our expertise in complex permittivity measurements enables detailed material characterization, supporting the development of innovative RF, microwave, and millimeter-wave technologies critical for next-generation sensing and communications sytems. The iEMSL comprises four specialized spaces: Instructional Lab and Visualization Studio (WEB 167), Metrology I and Anechoic Chamber (WEB 160/160A), Metrology II (WEB 164), and a machine shop (WEB 157).
Metrology I is also equipped with additive manufacturing tools and an open-range space allocated for short-range wireless and radar measurements. The laboratory offers industry-standard high-frequency measurement training for all users. Researchers are also welcome to use our assisted measurement service.
