  • MICROWAVE ABLATION ANTENNA SYSTEM

    An antenna system is provided. The antenna system includes a coaxial cable, an antenna, and an impedance matching structure. The coaxial cable includes a center conductor extending a length of the coaxial cable, a dielectric material surrounding the center conductor along the length of the coaxial cable, and a conductive shield surrounding the dielectric material along the length of the coaxial cable. The antenna includes a conductor having an electrical length of half a wavelength at a selected operating frequency. The impedance matching structure includes a second center conductor mounted between an end of the center conductor of the coaxial cable and a feed end of the antenna. The impedance matching structure is configured to match an impedance of the coaxial cable to an impedance of the antenna.

  • SPACE-TIME MICROWAVE IMAGING FOR CANCER DETECTION

    The imaging system (20) includes a microwave signal generator (21) which is supplied, on a line (22), with clock pulses from a clock (23). The output of the signal generator (21), which may be a short broadband pulses or a signal synthesized from multiple discrete frequencies, is provided on a line (27) to a directional coupler (28). The output of the directional coupler (28) is provided on a line (30) to a switching system (31) which selectively directs the power from the line (30) to lines (33) leading to each of the antennas (35) which are arranged in an array (36) antennas.

  • Subpicosecond electrodynamics of distributed Bragg reflector microlasers: Results from finite difference time domain simulations

    Hagness, Susan C.   Joseph, Rose M.   Taflove, Allen  

    With advances in nanofabrication techniques leading to ever smaller and more intricate semiconductor laser structures, a detailed understanding of the electrodynamics of these micron-scale devices is required in order to optimize their design. The finite difference time domain (FD-TD) Maxwell's equations solver holds much promise for providing highly realistic simulations of novel microcavity lasers. We have extended the FD-TD algorithm to include the effects of frequency-dependent gain and gain saturation. This approach and its application to the modeling of distributed Bragg reflector microlasers is presented

  • Remarks of Susan C. Schwab

    Susan C. Schwab  

    In conclusion, I am delighted to have this opportunity to contribute to the bold goals for the US India relationship envisioned by President Bush and Prime Minister Singh. My meetings to date with the Prime Minister, the Finance Minister and the Minister of Agriculture have all offered unique insights into the complex and exciting country that is India. My ongoing dialogue with my friend Kamal Nath is providing both of us with opportunities to expand the common ground that will benefit both of our peoples. And today marks my first opportunity to reach out and interact with India s exceptional business leaders. To exchange views and, above all, to enable me to listen and learn. The US India strategic partnership offers unlimited potential to make progress in development, trade and investment.

  • Susan C. Schwab: United States Trade Representative.

    The article discusses the contributions of the U.S.-China Business Council (USCBC) to the trade and economic relations between the U.S. and China. Major roles played by USCBC include expanding the U.S.-China trade, maintaining stable economy during times of political turbulence and urging the admission of China to the World Trade Organization (WTO). Moreover, since China's accession to the WTO, the country has become America's third-largest trading partner, fastest-growing major export market and fourth-largest customer in the world for American farm exports.

  • Remarks by Susan C. Schwab at

    Susan C. Schwab  

    1) What does America need to do to succeed in the global economy a) We need to engage not retreat. b) We needs to seize opportunities to open markets to U.S. goods and services as we stay open to the products of other countries. c) We need to foster cooperation with loyal allies and not rebuke their efforts to forge closer trade and investment ties. d) We need to raise the bar for how trade is conducted and shape its terms and standards so that trade s benefits will be broadly shared. e) We need to tackle thorny problems with diligent dialogue and unbending resolve and not use political tools for resolving economic disputes. f) And we need to address many of the issues underlying U.S. competitiveness that the IWF has focused on today. 2) This is the essence of what has been a highly successful seven years in our nation s trade history. We must complete the important work we have started and pave the way for future success. 3) As you grapple with how the United States can succeed in the global economy in this time of rapid change and closer integration, I urge you to keep in mind how important it is for veteran trading powers such as the United States and major new actors, such as China, to champion the benefits of the free and fair flow of commerce.
