Patent number: 6573737Abstract: The present invention relates to a method and apparatus for measuring material properties using guided-wave THz spectroscopy to measure the complex dielectric functions of materials. A high frequency wave is created and launched along a waveguide positioned in close proximity to a material under test. The wave is sampled initially, allowed to propagate, and sampled again. The samples are processed to derive information, such as resistivity, of the wafer. The method and apparatus of the present invention not only allows one to obtain information about the DC conductivity of metals, but also provides information about the high frequency behavior of materials—metals, and dielectrics as well—which is becoming particularly useful at the time when processor clocks are running at frequencies approaching GHz levels. The present invention provides for non-contact, non-destructive, non-contaminating testing.Type: GrantFiled: March 9, 2001Date of Patent: June 3, 2003Assignee: The Trustees of Princeton UniversityInventors: Stephen A.

Patent number: 6547940Abstract: A process directed to preparing surfactant-polycrystalline inorganic nanostructured materials having designed microscopic patterns. The process includes forming a polycrystalline inorganic substrate having a flat surface and placing in contact with the flat surface of the substrate a surface having a predetermined microscopic pattern. An acidified aqueous reacting solution is then placed in contact with an edge of the surface having the predetermined microscopic pattern. The solution wicks into the microscopic pattern by capillary action. The reacting solution has an effective amount of a silica source and an effective amount of a surfactant to produce a mesoscopic silica film upon contact of the reacting solution with the flat surface of the polycrystalline inorganic substrate and absorption of the surfactant into the surface. Subsequently an electric field is applied tangentially directed to the surface within the microscopic pattern.Type: GrantFiled: May 7, 2001Date of Patent: April 15, 2003Assignee: The Trustees of Princeton UniversityInventors: Ilhan A.

Patent number: 6535662Abstract: A Terahertz Optical Asymmetric Demultiplexer (TOAD) having preferably two non-linear elements (NLES) in which the extinction ratio is enhanced by saturating both NLEs when closing a switching window. A data signal input on one port of the TOAD is split onto two optical paths, each including one NLE. The optical paths converge at an output port. To start a switching window, a first control signal is input on an optical path that includes only one of the two NLEs. To close a switching window, one or more control signals are input such that both NLEs receive a control signal at a predetermined time after the first control signal is received by one of the NLEs. Only data signals passing through the first NLE during the switching window are output on the output port. Since both NLEs receive a second control signal at the same time, they decay together and thus avoid creation of unintended switching windows.Type: GrantFiled: March 9, 2001Date of Patent: March 18, 2003Assignee: The Trustees of Princeton UniversityInventors: Paul R. Prucnal, Ivan Glesk, Robert Runser, Christine Coldwell, Bing C. Wang

Patent number: 6418956Abstract: A pressure controller is provided for a pressure regulator. The pressure controller controls a pressure regulator to deliver process fluid at a regulated pressure from a variable supply. The pressure controller includes a control pressure source independent of the process fluid. One such pressure source could be compressed air which enters the controller through a restriction. The control pressure passes through the controller to the regulator where it exerts pressure on the pressure regulator. The controller is interconnected with the process fluid line at a point of regulation and senses pressure in a diaphragm chamber of the controller. A valve rides on the diaphragm and a bias is exerted against the valve to oppose pressure on the diaphragm. The bias tends to move the valve to a closed position. The bias means is adjustable. The process fluid pressure in the diaphragm chamber exerts a force on the diaphragm and valve, against the bias, to open the valve.Type: GrantFiled: November 15, 2000Date of Patent: July 16, 2002Assignee: Plast-o-Matic Valves, Inc.Inventor: Gerald Bloom
