An improved gas deposition chamber includes a hollow gas deposition volume formed with a volume expanding top portion and a substantially constant volume cylindrical middle portion. The hollow gas deposition volume may include a volume reducing lower portion. An aerodynamically shaped substrate support chuck is disposed inside gas deposition chamber with a substrate support surface positioned in the constant volume cylindrical middle portion. The volume expanding top portion reduces gas flow velocity between gas input ports and the substrate support surface. The aerodynamic shape of the substrate support chuck reduces drag and helps to promote laminar flow over the substrate support surface. The volume reducing lower portion helps to increase gas flow velocity after the gas has past the substrate support surface. The improved gas deposition chamber is configurable to 200 mm diameter semiconductor wafers using ALD and or PALD coating cycles. An improved coating method includes expanding process gases inside the deposition chamber prior to the process gas reaching surfaces of a substrate being coated. The method further includes compressing the process gases inside the deposition chamber after the process gas has flowed past surfaces of the substrate being coated.

A method and system for a plurality of airplanes in flight to receive from and send to a plurality of ground stations broadcast and communication signals through a single or a plurality of geostationary satellites, wherein at least the mobile link between said airplanes and said satellite, uplink or downlink, uses the high frequency radio waves at 17 GHz or higher, such as Ka-band. The fixed link between said satellite and said ground stations may use any radio frequencies below the frequencies used to communicate between the satellite and the aircraft. The lower frequencies tend to be less susceptible to rain attenuation and hence suitable for closing the fixed broadcast and communication link. Frequencies such as C-band or Ku-band, or even Ka-band, are applied between satellite and ground such that the available link margin is sufficient to overcome rain attenuation at said ground stations. Said satellite carries a plurality of transponders that may include a plurality of frequency converters to enable the conversion between different frequencies. Said satellite generates a plurality of spot beams, shaped or unshaped, which collectively cover the flight routes of said airplanes, preferably the geodesic path between two highly populated regions.

The present invention is directed to the manufacture of and the use of an aerodynamic flow control device having a compact array of a plurality of fluidic actuators in planar, curved, circular and annular configurations. The compact array of fluidic actuators of the invention may be designed to produce oscillating or pulsed jets at the exit ports with frequencies in the range of 1-22 kHz. They may be integrally manufactured along with the wing sections, flaps, tail and rudder of airplane, the inlet or exit geometries of a jet engine. When supplied with a source of fluid such as air, these arrays of actuators produce a set of fluid jets of random phase of high velocity and influence the main stream of air over the subject surface. The beneficial effects of modifying flow using the present invention include increased lift, reduced drag, improved performance and noise reduction in jet engines.
