The theory of scattering by an imperfectly conducting, dielectric or plasma sphere is reviewed briefly. Numerical values of the back scattering and forward scattering cross sections of spheres are given over wide ranges of the radius, the conductivity, and the permittivity including both positive and negative values. The angle of the electric field in the forward and backward directions is also represented. (Author).
Arrays of cylindrical dipoles and monopoles are usually driven by means of interconnecting transmission lines, whereas analyses of such arrays are generally made in terms of currents or voltages with assigned relative amplitudes and phases at the individual input terminals. Moreover, it is commonly assumed that the distributions of current along all elements are the same and without phase variation. In this report the properties of broadside and endfire arrays are treated with full consideration of interconnecting transmission lines and the effect of mutual coupling on the distributions of current. Driving-point admittances and field patterns of arrays of half-wave and full-wave elements are given. A novel broadside-endfire array is described. (Author).

This book covers the life and 60-year career of Prof. Benjamin Lax (1915-2015), a preeminent physicist at the Massachusetts Institute of Technology (MIT), who played major roles in the development and applications of solid state and plasma physics. In an extensive series of autobiographical interviews, Lax describes the challenges he overcame, the opportunities he embraced, and the many outstanding research physicists he recruited, mentored, and interacted with. He includes both personal and professional reminiscences. Lax begins with his earliest memories of his childhood in Hungary. He recalls the immigration of his family to America and his education in New York City. He describes his Arm...
