Certainly, microwaves would work: a test carried out in 2008 transmitted useful amounts of microwave energy between two Hawaiian islands 148km (92 miles) apart, so penetrating the 100km of the atmosphere would be a doddle.

当然,微波也能完成此项工作:2008年科研人员对微波做了实验,他们在两座相距148公里(92英里)的夏威夷岛屿之间成功地传送了大量微波能量,因此微波要穿透100公里的大气层也将是轻而易举的事。

在干燥空气与0.001  毫米的水汽水平的微波大气衰减。 The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly. The right half of this graph includes the lower ranges of infrared by some standards

微波英语:Microwave, 德语:Mikrowellen)是指波长介于红外线和无线电波之间的电磁波。微波的频率范围大约在 300MHz至300GHz之间。所对应的波长为1公尺至1mm之间。微波频率比无线电波频率高,通常也称为“超高频电磁波”。微波作为一种电磁波也具有波粒二象性。微波的基本性质通常呈现为穿透、反射、吸收三个特性。对于玻璃、塑料和瓷器,微波几乎是穿越而不被吸收。对于水和食物等就会吸收微波而使自身发热。而对金属类东西,则会反射微波。

微波在雷达科技、ADS射线武器、微波炉、等离子发生器、无线网络系统(如手机网络、蓝牙、卫星电视及无线局域网路技术等)、传感器系统上均有广泛的应用。

A telecommunications tower with a variety of dish antennas for microwave relay links  on Frazier Peak, Ventura County, California.
The atmospheric attenuation of microwaves and far infrared radiation in dry air with a precipitable water vapor level of 0.001 mm. The downward spikes in the graph correspond to frequencies at which microwaves are absorbed more strongly. This graph includes a range of frequencies from 0 to 1 THz; the microwaves are the subset in the range between 0.3 and 300 gigahertz.
Cutaway view inside a cavity magnetron as used in a microwave oven (left). Antenna splitter: microstrip techniques become increasingly necessary at higher frequencies (right).

Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm). This broad definition includes both UHF and EHF (millimeter waves), and various sources use different boundaries. In all cases, microwave includes the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum, with RF engineering often restricting the range between 1 and 100 GHz (300 and 3 mm).
