Control of the electromagnetic spectrum is a critical challenge in electronic warfare due to its fundamental role in modern communications, sensing and weapon systems. Electromagnetic spectrum control allows military forces to deny or disrupt enemy communications, radar and other electronic systems, degrading their ability to operate effectively.

Additionally, controlling the spectrum enables the use of electronic countermeasures to protect friendly forces from enemy attacks and surveillance. As technology advances, the spectrum becomes increasingly congested, making effective spectrum management and dominance even more crucial for military success.

Emerging microwave photonics capabilities offer promising solutions for ensuring control of the electromagnetic spectrum. Critical Frequency Design applies advanced photonics to address the challenges of EW systems, including tools for wideband frequency conversion and wideband interference suppression.
