GLOVIEW is a registered development partner of Hyundai Motor Namyang R&D and the official Korean agent of Guangzhou Nano-metal. We supply cores to Korean automotive Tier 1–2 manufacturers and shielding parts to EMC and defense facilities in Korea and overseas.
EMC chamber
Inside an EMC shielded room.
Ferrite absorbers handle the low band on the walls. Pyramid absorbers are added in a hybrid configuration above 1 GHz. Shielded rooms and doors are designed and quoted after the site specification is confirmed.

Absorber coverage by frequency
Ferrite absorbers cover the lower band; pyramid absorbers are added in a hybrid configuration above 1 GHz.
Manufacturer: HCA Corporation
The HFT Series is HCA's flagship RF absorber, built for the 30 MHz to 1 GHz range. It is used on its own or combined with hybrid pyramidal absorbers, in new anechoic chambers and in upgrades of existing EMC facilities. Each tile is precision machined and surface ground on all six sides to reduce gaps between adjacent tiles.
Specifications
| Frequency range | 30 MHz to 1 GHz (VHF and UHF bands) |
|---|---|
| Material | Fire-resistant sintered ferrite |
| Machining | Surface ground on all 6 sides |
| Mounting hole | 10 mm |
| Available panel size | 600 × 600 mm |
| Compliance | REACH and RoHS |
| Warranty | 35 years (stated by HCA) |
Features
- Good impedance match for use with hybrid absorbers
- Precision machined to strict mechanical tolerances
- Nonflammable sintered ferrite
- Screwed to the wall through the 10 mm hole, or attached with adhesive
- Ultra-thin, so it takes little space inside a shielded enclosure
Applications
- EMC anechoic chambers: radiated emission and immunity testing, new builds and upgrades
- Dark boxes for mobile phone inspection
- TV ghost prevention: UHF reflection attenuation in high-rise buildings
- RFID interference prevention for UHF readers in industrial settings
- Automotive and IoT testing, including self-driving car sensors and drones
- Plane-wave reflection attenuation in existing RF shielded rooms
Thickness and reflectivity values are not published on the product page. Contact us for the datasheet.

Manufacturer: HCA Corporation
HCA makes pyramidal absorbers for EMC chambers and develops its own ferrite tiles to work with them. Together they form what HCA calls a harmonized EMC solution. EMC testing identifies and reduces unintended electromagnetic emissions so that devices meet regulatory standards.
Standards and application areas
| Standard | Application area | Notes |
|---|---|---|
| CISPR 16-1-4 | (FS)NSA / sVSWR | Pre-compliance testing up to 10 m, in semi-anechoic chambers and fully anechoic rooms |
| IEC 61000-4-3 | Field uniformity | Uniform field distribution |
| CISPR 25 / ISO 11452 | Automotive component | Component testing chambers |
| CISPR 12/25 / ISO 11451 | Full vehicle | Full vehicle chambers |
