Feed positioning in the way that its phase center exactly coincides with the focus of the offset parabola and its direction so that the radiation maximum falls in the geometric center of the elliptic reflector surface are not intuitive at all, as in classic parabolic antennas.

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

And you can even have lots of repeaters sort of dialing into one reflector.

你甚至可以讓許多種中繼器撥號(hào)給一個(gè)反射器。

The objective is to use available objects such as rocket, bomb, reflectors, launchers to clear your way to the exit.

The secondary edge reflector is shaped and arranged with respect to the heating array and the susceptor for re-directing the misdirected thermal radiation to the outer edge of the susceptor.

二次邊緣反射器相對(duì)于加熱行列和襯托器而被成形并布置亚洲中字乱伦一区二区，可用來(lái)將誤導(dǎo)的熱輻射重新導(dǎo)向襯托器的外邊亚洲欧美日韩一区二区在线。

Further, the reactor includes a secondary edge reflector having a specular surface positioned beside the heating array for recovering misdirected thermal radiation directed generally to a side of the heating array and away from the susceptor.

此外還包括二次邊緣反射器，它有一個(gè)位在加熱行列旁邊的鏡面可用來(lái)回收一般導(dǎo)向加熱行列的一側(cè)并離開襯托器的誤導(dǎo)的熱輻射日韩系列在线精品视频观看。

Thus, the secondary edge reflector heats the edge and reduces thermal gradients across the susceptor and the semiconductor wafer to inhibit slip dislocations in the wafer during epitaxial layer deposition.

這樣www黄片com，二次邊緣反射器便可加熱外邊并減小橫越襯托器和半導(dǎo)體晶片的熱梯度，從而可在外延生長(zhǎng)層沉積時(shí)阻止晶片內(nèi)滑移位錯(cuò)的發(fā)生久久精品亚洲精品无码白。

All these accessories, plus a model rifle, were tagged with retroreflectors, which can reflect a beam of radiation back to its source regardless of the angle of incidence.
