Superconductive electromagnetic shielding sealing strip

Product Specifications

Product Features

1. Broad-Frequency Coverage
Offers unparalleled shielding performance across an extremely wide frequency spectrum, from Direct Current (DC) magnetic fields to very high-frequency (microwave, THz) radiation.

2. Zero-Resistance Operation
In its superconducting state, the material has no electrical resistance, eliminating energy loss due to Joule heating during operation.

3. Active Shielding Capability (Potential)
Can be integrated with superconducting coils to create an active shielding system that generates counter-magnetic fields for dynamic and adaptive EMI cancellation.

4. Critical State Dependency
Its superconducting (and shielding) state is maintained within specific thresholds of temperature, magnetic field, and current. Performance is lost if these critical values are exceeded.

5. Material & Construction
Typically made from high-temperature superconductor (HTS) materials (e.g., YBCO). Designed as a flexible strip, potentially incorporating internal cooling channels for cryogenic operation and an external protective jacket for durability.

Application

● Magnetic Resonance Imaging (MRI) & NMR
Shielding for next-generation, high-field systems to improve image fidelity and stability.

● Satellite & Spacecraft Electronics
Protecting avionics and sensors from intense cosmic and man-made radiation.

● SQUID-based Systems
Essential for shielding Superconducting Quantum Interference Devices (SQUIDs) used in Magnetoencephalography (MEG) and Magnetocardiography (MCG) to measure extremely weak biological magnetic fields.

Advantages

1. Unmatched Shielding Performance
Achieves shielding effectiveness (SE) values that are orders of magnitude higher than copper, aluminum, or Mu-metal, creating a near-perfect "electromagnetic vacuum."

2. Zero Power Loss for Magnetic Shielding
The expulsion of DC and low-frequency magnetic fields (Meissner Effect) consumes no energy, unlike conventional shields which suffer from eddy current losses.

3. Ideal for Ultra-Sensitive Environments
Generates virtually no inherent thermal or Johnson-Nyquist noise, making it perfect for protecting the most sensitive electronic and quantum devices.
