Microwave absorbers have evolved significantly since their inception. DMAS has established itself as a leader in the microwave absorber industry, with products that offer unmatched durability, performance, and environmental responsibility. Their absorbers provide a sustainable, long-lasting solution for industries that rely on precise testing, making them a top choice for antenna testing and EMC applications. Since the introduction of their microwave absorbers in 2011, DMAS has continuously innovated, offering products that not only perform exceptionally but are also built to last. 

DMAS absorbers are known for their impressive lifespan, with a product life cycle of over 25 years. This longevity is made possible by the closed-cell structure of the polystyrene (EPS) material, which ensures stable performance over time. With consistent performance, these absorbers provide a reliable and reproducible testing environment, making them ideal for industries that rely on precision.

High-Performance and Versatile Absorbers for Multiple Applications

One of the standout features of DMAS absorbers is their broad operating frequency range, from 200 MHz to 50 GHz. This makes them suitable for a variety of applications, from RF and antenna testing to EMC testing environments. The DMAS MT absorber series is specifically designed for compact antenna ranges, while their hybrid absorbers cater to more specialized electromagnetic compatibility (EMC) testing. While their Javelin Tip (JT) absorbers, have pushed the boundaries of performance while ensuring durability and sustainability.

Their superior reflectivity at microwave frequencies makes DMAS absorbers a trusted choice for testing environments where accuracy and performance are critical. For those looking for detailed specifications, DMAS provides brochures featuring performance graphs and in-depth technical details.

DMAS Prioritizes Sustainability and Clean Technology

In today’s testing environments, sustainability is becoming increasingly important, and DMAS has responded by creating microwave absorbers that meet the highest environmental standards. The materials used in DMAS products are REACH and RoHS compliant, ensuring they are free from hazardous substances, making them safe and environmentally responsible.

The modular design of DMAS absorbers also contributes to their sustainability. If a part of the absorber, such as a pyramid, is damaged, it can be replaced individually, rather than requiring the replacement of the entire unit. This not only reduces waste but also lowers costs for users.

One of the common issues with traditional foam-based absorbers is the leakage of carbon particles, which can create a mess in the testing environment. DMAS absorbers are designed to prevent this, ensuring that laboratories remain clean and free of contaminants throughout the product’s life cycle. This makes them a practical and clean solution for long-term testing needs.

Fire Retardant and Resistant to Humidity

Another important feature of DMAS microwave absorbers is their resistance to environmental factors like humidity and fire. These absorbers are designed to be fire retardant, making them safer for use in various testing environments. Additionally, they maintain their performance even in fluctuating humidity conditions, further ensuring their durability over time.

For those interested in the technical advantages of EPS-based materials over traditional foam, DMAS offers resources that compare the two in terms of performance, cleanliness, and sustainability. These comparisons highlight why DMAS absorbers are considered the best choice for modern RF and microwave signal attenuation.

With a 25-year warranty, broad operating frequency range, and fire-resistant, eco-friendly design, DMAS microwave absorbers are at the forefront of innovation. As testing environments continue to evolve, DMAS remains committed to delivering solutions that meet the highest standards of performance, sustainability, and safety.
