The book presents solutions to a complex of internal and external problems of electromagnetics associated with the development of theory, construction of mathematical models and the development of rigorous methods for calculating the electrodynamic characteristics of combined vibrator-slot structures. The solutions of problems for determining the characteristics of impedance vibrator and slot radiators with arbitrary geometric and electrophysical parameters presented in the monograph were obtained within the framework of the unified methodological approach to construct asymptotic solutions of integral equations on currents and their systems. This approach made it possible to study a number of new combined vibrator-slot structures. The research results reveal the possibilities of using such structures as basic elements in the creation of modern antenna-waveguide devices operating in the ranges from meter to millimeter wavelengths, with new technical characteristics and functional purpose. The book is intended for senior and postgraduate students and researchers working in the fields of radiophysics, radio engineering and antenna-feeder design. The book covers the following topics: • excitation of electromagnetic waves in volumes with coordinate boundaries;• general issues of the theory of thin impedance vibrators and narrow slots in a spatial-frequency representation;• solution of current equations for isolated vibrator and slot scatterers;• combined radiating vibrator-slot structures in rectangular waveguide;• T-junctions of rectangular waveguides with vibrator-slot structures in coupling areas;• waveguide radiation of the combined vibrator-slot structures;• combined vibrator-slot structures located on a perfectly conducting sphere;• combined vibrator-slot Radiators in antenna arrays;• ultrawideband vibrator-slot structures;

This book presents a review of the work of the architect Michael Balz, pioneer of concrete-shell architecture. It discusses his projects, both realized and unbuilt, many being designed in collaboration with the renowned Swiss engineer Heinz Isler. Profusely illustrated with original drawings and photographs, Michael Balz: Shells and Visions caters to the increasing interest in the design and construction of free-form reinforced concrete shells consequent on the advent of 3D modelling and form-finding software. The book describes architectural designs and practical construction issues to motivate contemporary shell designers. Balz’s experience of dealing with such difficulties as incompatibility with non-structural features and the insertion of windows into shells, and the assessment of buildings’ long-term performance allow readers to learn more easily how to cope with such issues in their own work. The book introduces Michael Balz, his early work with other architects, including his work on pneumatic forms with Frei Otto, and his evolution into an exponent of organic architecture. It then discusses completed projects, including the outdoor Theater unter den Kuppeln (1976), Ballettsaal (1979) and Balz House (1981). Competitions Balz entered and unrealized shell projects also receive attention, as does his work on the urban scale, highlighting conceptual designs of mega-cities. His visionary megastructures encourage the exploration of innovative solutions for city spaces by architects faced with today’s increased urbanization. Michael Balz: Shells and Visions will be of interest to students and professionals in the fields of architecture, structural engineering, building and urban design. It’s reflections on the cultural and contextual aspects of Balz’s work will help the architectural historian to appreciate its long-term significance.

This book provides an essential overview of wind science and engineering, taking readers on a journey through the origins, developments, fundamentals, recent advancements and latest trends in this broad field. Along the way, it addresses a diverse range of topics, including: atmospheric physics; meteorology; micrometeorology; climatology; the aerodynamics of buildings, aircraft, sailing boats, road vehicles and trains; wind energy; atmospheric pollution; soil erosion; snow drift, windbreaks and crops; bioclimatic city-planning and architecture; wind actions and effects on structures; and wind hazards, vulnerability and risk. In order to provide a comprehensive overview of wind and its manifold effects, the book combines scientific, descriptive and narrative chapters. The book is chiefly intended for students and lecturers, for those who want to learn about the genesis and evolution of this topic, and for the multitude of scholars whose work involves the wind.

This well-illustrated book—in color throughout—presents a thorough introduction to the mathematics of Buckminster Fuller’s invention of the geodesic dome, which paved the way for a flood of practical applications as diverse as weather forecasting and fish farms. The author explains the principles of spherical design and the three main categories of subdivision based on geometric solids (polyhedra). He illustrates how basic and advanced CAD techniques apply to spherical subdivision and covers modern applications in product design, engineering, science, games, and sports balls.
