Kymeta's Breakthrough in Multi-Band Antenna Satellite Connectivity
Kymeta achieved a major breakthrough for the satellite communications industry recently by connecting four concurrent beams in Ku- and Ka-band frequencies with a single antenna aperture, during a demonstration in April. Enabled by the company's unique metamaterials antenna surface, the technology was demonstrated and validated at Kymeta's headquarters in Redmond, Washington. Until this point, according to Kymeta, interoperability in the Ku and Ka bands has been possible only with Electronic Steered Antennas (ESA) using multiple physically separate antennas, which proves problematic due to the size and power usage required to operate. Kymeta Chief Scientist Ryan Stevenson is the guest on this episode of the Aerospace & Defense Technology podcast to explain how they were achieved this groundbreaking demonstration of satellite communications.

Simulating Space: Designing Satellites for Mission Success
During his appearance at a Center for Strategic & International Studies (CSIS) event held in March, Major General Gregory Gagnon, a top U.S. Space Force official, said that the U.S. Space Force expects to launch more than 100 satellites in 2025. Have you ever considered the challenges of operating inspace that companies must address when designing satellites for military and non-military applications? In the latest issue of Ansys Advantage, simulation software provider Ansys outlined these considerations in their article "The State of Satellites: Applications, Challenges and Opportunities."According to Patrick North, Principal R&D Engineer, Ansys, said that "power, space, and weight" are the primary factors that systems engineers must consider when designing new satellites. North is the guest on this episode of the Aerospace & Defense Technology podcast to explain how major aerospace and defense companies use their advanced simulation softwareand tools to design and model defense satellites for a wide variety of applications.

How Amprius is Advancing Energy Density for Electric Aircraft Batteries
Amprius recently launched its 450 Wh/kg SiCore™ lithium-ionbattery, the most energy dense battery it has ever developed for electric aircraft and other mobility applications. The California-based lithium-ion battery maker has made several advancements in battery energy density with its silicon anode material system, and is now preparing to move to mass production of SiCore. The commercial launch of the 450 Wh/kg SiCore™ cell followsthe broader introduction of Amprius’ SiCore™ platform in January 2024. That announcement marked the debut of a new generation of silicon anode cells engineered for both high energy and high power in a single format. Their lithium-ion batteries have already demonstrated the ability to extend the range and flight times of drones and high-altitude platform stations (HAPS). The company is now focused on mass producing their lithium ion battery to support more aviation and defense applications. Amprius CTO Dr. Ionel Ștefan is the guest on this episodeof the Aerospace & Defense Technology podcast to explain their latest battery energy density breakthrough and how they're preparing for mass production of their batteries.
