Abstract
A method and system for selectively varying the performance of a test chamber are disclosed. According to one aspect, the performance is affected by a variable absorbing structure of the test chamber. The absorbing structure enables selective exposure of absorbing material to achieve a specific performance.
Claims20
A variable absorbing structure of a test chamber, the structure comprising:
- reflective material;
- and
- absorbing material at least partially shielded by the reflective material, the reflective material being adjustable to expose at least a portion of the absorbing material.
A method for affecting performance of a reverberation chamber, the method comprising:
- positioning a variable absorbing structure within the reverberation chamber at a predetermined position and orientation to achieve a repeatable specific performance.
A test chamber, comprising:
- an enclosed housing with at least one at least partially reflective interior wall;
- and
- an absorbing structure having absorbing material, the absorbing structure configured to selectively expose the absorbing material to achieve a repeatable specific performance.
