| 11. | The radiation zone is important because far fields in general fall off in amplitude by.
|
| 12. | A compact range is an anechoic chamber with a reflector to simulate far field conditions.
|
| 13. | See near and far field and multipole expansion.
|
| 14. | However, because they are in the far field, their angular distribution does not change with distance.
|
| 15. | This distance can be a far distance at low frequencies, and is called the far field.
|
| 16. | The far field is the region in which the field acts as " normal " electromagnetic radiation.
|
| 17. | They had worked only in the far fields since Serbs fired on farmers at work, wounding four.
|
| 18. | The region extending farther than about 2 wavelengths away from the source is called the far field.
|
| 19. | More precisely, the van Cittert Zernike theorem requires that we observe the source in the so-called far field.
|
| 20. | On the other hand, the far field distance from a PSF spot is on the order of ?.
