| 1 | The radiation takes the form of high-frequency gamma rays. | |
| 2 | Such structures could be used in applications like solar cells or high-frequency devices. | |
| 3 | They work by sending out pulses of high-frequency sound and then interpreting the reflections as images. | |
| 4 | This was why the quakes were felt so broadly, and why there have been such frequent aftershocks. | |
| 5 | This will enable the next generation, high dynamic range mixed signal technology and high frequency RF power sources. |
