Disadvantages of absorbing waves of high magnetic materials

Disadvantages include weight, cost and complexity.

1. weight: High magnetic materials are usually very heavy, which will increase the weight of the whole structure and may not be ideal for some applications.

2. Cost: High magnetic materials are usually expensive, which will increase the project cost.

3. Complexity: The preparation process of high magnetic materials is relatively complex, requiring precise technology and equipment, which increases the difficulty of production and processing.
