  • Application of the optimization method to the point-to-point radio wave ray-tracing problem

    Publication Year: 2017, Page(s):14 - 19

    Point-to-point ray tracing is an important problem in many fields of science. In direct variational methods, some trajectory is transformed to an optimal trajectory. While these methods are routinely used in calculations of pathways of seismic waves, chemical reactions, diffusion processes, etc., these approaches are not widely known in ionospheric point-to-point ray tracing. A two-dimensional rep... View full abstract»

  • Suppression of multi-path couplings in scaled-down experiment for cross-borehole pulse radar

    Publication Year: 2017, Page(s):20 - 25
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (887 KB)

    A scaled-down experiment using cross-borehole pulse radar was performed in a laboratory to extract a more precise decision rule for detecting an intrusive manmade tunnel in Korea. To minimize the total size, a scaled-down model of an air-filled tunnel in underground rock was replaced by a cylindrical ceramic rod in pure water. When the upper arm of a sleeve-dipole antenna of the scaled-down cross-... View full abstract»

  • RF output-power enhancement by optical-pulse compression in photonic-based RF generation

    Publication Year: 2017, Page(s):26 - 33
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (589 KB)

    In photonic-based RF generation, the RF output power is limited by the average optical power to the photodetector (PD). It is known that the RF output power is enhanced by use of a narrow optical pulse at the photodetector, whereas the average power to the photodetector is the same. In this paper, we propose to use optical-pulse compression in a standard optical fiber in order to enhance the RF ou... View full abstract»

    Quantum-communications technologies, especially involving teleportation, will play an increasingly important role in both the domestic and defense sectors because of the promise for improved security, distributed quantum computing, and quantum sensing. This paper presents a review of this emerging field, summarizing key protocols as well as some representative quantum teleportation experiments con... View full abstract»

    The Copernicus program (previously known as GMES: Global Monitoring for Environment and Security) is a major European undertaking for the continuous monitoring the Earth system. Copernicus is one of the two pillars — together with the Galileo program — of the cooperation between the European Union (EU), the European Space Agency (ESA), and their Member States. This paper describes the implementati... View full abstract»

    I guess you can call me a box collector. I save almost all of the boxes that we get from Amazon and put them in our basement. Whenever we send presents to grandchildren or other relatives, I pick out an appropriately sized box to contain the gifts. We do not buy presents based on the size of the boxes that lie in the basement; however, we have not had to buy any boxes, because I maintain an adequa... View full abstract»

    Photonic crystals are well-known electronic devices that enable modification, transformation, and selection of light or, more generally, electromagnetic waves [1]. Even though they have a long history of more than 100 years, these structures are becoming increasingly popular, thanks to the rapid developments in nanotechnology and material science, enabling the design and fabrication of very small ...

    Presentations at conferences play an essential role in the dissemination of new ideas, and are often triggers for fruitful discussions between scientists. However, giving an effective oral presentation is not easy. We can probably all remember how we felt when we stepped on the stage in front of a room full of people for the first time. Even the early-career researchers reading this column have li... View full abstract»

    In February, I was invited by the Research Organization of Information and Systems (ROIS) Female Research Development Office to spend some time in Japan. The Japanese government has gotten interested in promoting gender equality in science through its research organizations. For example, one of the purposes of my visit was to tell how Sweden is striving towards gender balance in academia. View full abstract»

    Alhough I had some ambiguous interest in the origins of life and of the universe in my childhood, I naively believed that I would be a teacher for local schools because I had good familiar examples, including my father. However, a happy encounter during high school led me to make up my mind to study geophysics, and auroral physics, in particular. It was a book written by Dr. Kazuyo Sakanoi, who st...

    Welcome to this new column on education. In some capacity or other, all radio scientists are in many ways perpetual learners and teachers. Thanks to the interdisciplinary nature of radio science (which makes it so exciting), and the fast evolving developments in this colorful field, keeping abreast with evolving frontiers of knowledge is not only a challenge, but also a requirement.
