What ASMI does

ASMI (Advanced Stealth Materials Inc., 애즈미 주식회사) is a private South Korean defense materials company founded in August 2021 as a laboratory spin-off from Yonsei University's Optical Stealth Material Laboratory (OSML) under Professor Han Jae-won (J.W. Hahn). The company commercializes a proprietary plasmonic metamaterial architecture deposited on flexible ~200μm substrates to absorb multiple threat-relevant spectra simultaneously, including laser guidance bands, near-infrared, mid/long-wave infrared, and dual-band millimeter-wave radar signals.

Its core offering is a four-product portfolio of multi-band stealth materials: Type A (Dual-Band Infrared Stealth Material), Type B (Infrared Stealth Camouflage Material with customizable RGB camouflage), Type C (Radar & Infrared Bi-Stealth Material), and Type D (Transparent Bi-Stealth Material for vehicle and building windows). These products are positioned as lighter, more uniform, and more broadband-capable substitutes for conventional stealth paint coatings and fiber-based RAM materials, with stated integration targets on South Korean defense platforms including K2 main battle tanks, K9 self-propelled artillery, and Redback infantry fighting vehicles.

ASMI's business model is direct enterprise B2B sales and licensing to South Korean defense manufacturers and military procurement agencies, supplemented by government-backed R&D. The company has secured a TIPS Program investment and operates under the Ministry of Science and ICT's Future Defense Innovation Technology Development Program. Pricing is not publicly disclosed, consistent with a quote-based defense procurement model, and the company has 1-10 employees with no revenue disclosed and only prototype-scale production to date. It is currently single-geography (South Korea, headquarters at Yonsei University in Seoul).

Core offering

ASMI develops and manufactures advanced multi-spectral stealth materials based on plasmonic metamaterial nanotechnology for defense applications. Its product line includes four types of stealth materials (Type A dual-band infrared, Type B infrared camouflage, Type C radar and infrared bi-stealth, and Type D transparent bi-stealth) designed to protect military equipment, vehicles, personnel uniforms, and building windows from laser-guided, infrared thermal imaging, and millimeter-wave radar-guided weapons.

Product overview

ASMI offers a portfolio of four multiband stealth material products based on advanced metamaterial technology. Type A and Type B focus on infrared stealth applications, with Type A providing dual-band infrared protection for countermeasure systems and Type B adding camouflage coloring capabilities. Type C combines radar and infrared bi-stealth functionality for comprehensive multi-band protection, while Type D provides transparent stealth solutions for vehicle and building windows. All products are designed to protect stealth objects from various advanced guided weapons including laser-guided, infrared thermal image, and millimeter-wave radar guided weapons.

Products and services

• Type A Dual-Band Infrared Stealth Material Material that absorbs the Near-Infrared band, reduces Medium/Long Wavelength Infrared Radiation, and emits to the atmospheric absorption band. Applied to counter Laser Guided Weapons and Infrared Thermal Image Weapons on military platforms.
• Type B Infrared Stealth Camouflage Material Material that absorbs the Near-Infrared band and reduces Medium/Long Wavelength Infrared Radiation. Can materialize Red, Green, and Blue colors mimicking camouflage patterns for application to ground weapons systems and military uniforms.
• Type C Radar & Infrared Bi-Stealth Material Flexible, lightweight, thermal-resistive material that absorbs Dual Band MMW Radar and Near-Infrared band signals and reduces Medium/Long Wavelength Infrared Radiation. Designed to respond to MMW active Radar Guided Weapons and Laser Guided Weapons on military platforms.
• Type D Transparent Bi-Stealth Material Flexible, lightweight, transparent material that reduces Medium/Long Wavelength Infrared Radiation and absorbs Dual Band MMW Radar signals, with electromagnetic shielding properties. Used as windows for military vehicles or buildings.
