摘要： The magnetic force between the electromagnet and plunger of a magnetic actuator, the electromagnet including a coil generating magnetic flux when the coil is energized, can be increased by locating a near field plate on the electromagnet. The near field plate has a spatially modulated surface reactance configured to focus the magnetic flux within a region of the plunger, such as the central portion of an end portion of the plunger proximate the electromagnet, so as to increase the magnetic force between the electromagnet and plunger. Examples also include permanent magnet based actuators and the use of other magnetic field focusing devices.

摘要： Ten radiation antenna elements project from a straight feeder stripline. A first set of radiation antenna elements each having a rectangular shape project from a first side edge of the feeder stripline such that the radiation antenna elements incline at an angle of about 45 degrees. The distance between adjacent radiation antenna elements is equal to an guide wavelength &lgr;g and the length of each radiation antenna element is equal to &lgr;g/2. Similarly, a second set of radiation antenna elements each having a rectangular shape project from a second side edge of the feeder stripline. Each of the radiation antenna elements in the second set is disposed to be separated by &lgr;g/2 from a corresponding one of the radiation antenna elements in the first set. Each of the radiation antenna elements is connected to the corresponding side edge of the feeder stripline via a corner thereof.

摘要： A light switch (or valve) made up of two mutually inverted, substantially identical diffraction gratings with a liquid medium therebetween, arranged to allow the grating substrates to be shifted laterally relative to one another so as to align and mis-align the grating elements. When aligned, incident-polarized light passes through the switch and when misaligned, light does not pass through the switch but is reflected.
