Scattering-angle-dependent Christiansen color spectra data of poly(vinyl chloride) (PVC) suspended in styrene liquid and a comprehensive data list of wavelength-dependent refractive indices of PVC.
Data in brief, 2018Co-Authors: Sadaki Samitsu, Hideki T. Miyazaki, Hiroyo SegawaAbstract:Abstract This paper reports transmission and scattering spectra of poly(vinyl chloride) (PVC) in styrene liquid, which is derived from Christiansen effect. The spectra were measured by varying scattering angles. Further discussion on Christiansen color was provided in the paper entitled "Transmitting and scattering colors of porous particles of poly(vinyl chloride) based on Christiansen effect" (Samitsu et al., 2018) [1]. The paper additionally provides refractive indices of PVC reported in literatures because Christiansen effect has close relationship with wavelength-dependent refractive index, i.e. optical dispersion. The values have considerable range probably depending on samples and determination methods for refractive index. The comprehensive data list is therefore potentially useful for studying refractive index of polymers.

Transmitting and scattering colors of porous particles of poly(vinyl chloride) based on Christiansen effect
Polymer, 2018Co-Authors: Sadaki Samitsu, Hideki T. Miyazaki, Hiroyo SegawaAbstract:Abstract Porous poly (vinyl chloride) (PVC) particles immersed in organic liquids exhibited bright colors when the refractive indices (RIs) of the liquids were close to the RI of PVC. The particles can separate white light into complementary transmitting and scattering colors. Unlike conventional structural colors resulting from interference of light, the colors, which are independent of the periodic microstructures, were systematically tuned by varying the wavelength-dependent RIs of liquids and covered the entire visible range from 320 to 780 nm. Numerical calculation based on the Mie scattering theory successfully reproduced their transmission spectra, validating the Christiansen effect of these materials. The RI determined by this effect was higher than that of the film sample and representative values in literature. The study reveals new and undiscovered RI-related features of polymers and demonstrates that the Christiansen effect will provide a simple but valuable method to study the dispersion state of polymer particles in liquids.

Chris Christiansen: Telescope Design and Earth-Rotational Synthesis
Four Pillars of Radio Astronomy: Mills Christiansen Wild Bracewell, 2017Co-Authors: R. H. Frater, W. M. Goss, H. W. WendtAbstract:Wilbur Norman “Chris” Christiansen (1912–2007) is remembered for his invention of the grating array radio telescope that he used for solar observations and for the first application of earth-rotational synthesis to produce a two-dimensional image of the sun.

Wilbur Norman Christiansen 1913-2007
arXiv: History and Philosophy of Physics, 2011Co-Authors: R. H. Frater, W. M. GossAbstract:W. N. ('Chris') Christiansen was an innovative and influential radio astronomy pioneer. The hallmarks of his long and distinguished career in science and engineering, spanning almost five decades, were his inventiveness and his commitment to, and success with, large-scale projects. These projects were the outcome of his innovative skill as physicist and engineer. Paralleling this was his equal commitment to forging strong international links and friendships, leading to his election as Vice-President of the International Astronomical Union for the years 1964 to 1970, as President of the International Union of Radio Science, URSI, from 1978 to 1981, and subsequently as Honorary Life President in 1984, and as Foreign Secretary of the Australian Academy of Science from 1981 to 1985. Major subsequent developments in radio astronomy and wireless communications on the global scene stand as a legacy to Chris's approach to his work and to the development of those who worked with him.
