In 2024, General Stephen Whiting, the commander of U.S. Space Command opposed the sale of both the 3.1 to 3.45 GHz and the 7.0 to 8.0 GHz parts of the electromagnetic spectrum when he testified ...

The electromagnetic spectrum is a rainbow of light waves that surround us — but we only see a small part of it. From radio waves to gamma rays, each type of light has its own properties and uses. By ...

The next electromagnetic spectrum band after radio waves are microwaves. As microwaves cover wavelengths between 3.3 feet and 0.04 inches (1 meter and 1 millimeter), ...

A bipartisan group of lawmakers who co-chair the Congressional Electromagnetic Warfare Working Group said the Defense Department needs to take more of an active role in enhancing its spectrum use ...

Based on observations from the war in Ukraine, we need to place a sense of urgency on spectrum and survivability on the battlefield. The Multi-Function Electronic Warfare-Air Large's purpose and ...

The Pentagon needs to change its passive approach to spectrum management, EW capabilities, said bipartisan chairs of the Congressional Electromagnetic Warfare Working Group.

The US Army conducted a joint-force, multinational training in Hawaii earlier this month. Troops focused on how to be "small and undetectable" in the electromagnetic spectrum, a commander said.

If the wavelength of this electromagnetic wave is very long (greater than 10 meters), we call it a radio wave. For shorter waves, in the range of 1 millimeter to 1 meter, that would be a microwave.

Therefore, the superior electromagnetic wave absorption performance of the SiOC/Ag composite can be achieved by the synergistic effects of multiple reflections, conductive loss and interfacial ...
