This book addresses microwave researchers, engineers, and Master's and Ph.D. students. It follows the idea of the first Edition to educate the readers on fundamental electromagnetics and show how this brilliant theory is used in developing modern multi-physics microwave and terahertz hardware.

This book is a record of a seminar on mathematical logic Kurt Gödel and Hans Hahn held in Vienna in 1931-32. The seminar proceedings, given in English translation, are a unique witness of the state of research in logic and foundations of mathematics right after Gödel had published his celebrated incompleteness theorems. The seminars explain Gödel's results in logic in detail, in contrast to his publications of the time that often were quite laconic and extremely short. This book also contains Gödel's trial lecture on intuitionistic logic held in Vienna in 1933. The manuscript, recently found among the Gödel papers kept in Princeton, is preserved in Gödel's forgotten German shorthand and published here in an English translation.

This book selectively defines the current state of technological development of the Ukrainian economy and the prospects for the deployment of energy-efficient technologies in the energy and transport spheres, in particular, in aviation. On the path of its socio-economic development, Ukraine has repeatedly passed through crisis moments that changed the scenarios and trends of the country's development. Today, Ukraine has to evaluate survival scenarios and, in extreme conditions, revise plans for the country's further development. The energy sector in Ukraine and the world exists in a dynamic environment and changes in response to internal and external challenges. Technological solutions for deploying the transition to clean renewable energy sources are already widely available in today's world and continue to develop rapidly. In Ukraine, the problem of energy transition is given special urgency and acuteness by the threat to energy security. The state of Ukraine's traditional energy industry determines the need to reach a modern technological level with the use of innovative renewable technologies for energy production. Increasing the level of domestic energy efficiency will contribute to the diversification of energy supply of central and distributed energy generating systems, which will ensure the creation of a low-carbon national economy and increase the role of domestic energy in the system of international cooperation, including access to international markets of energy goods and services.

This book provides fundamental principles, design procedures, and design tools for unmanned aerial vehicles (UAVs) with three sections focusing on vehicle design, autopilot design, and ground system design. The design of manned aircraft and the design of UAVs have some similarities and some differences. They include the design process, constraints (e.g., g-load, pressurization), and UAV main components (autopilot, ground station, communication, sensors, and payload). A UAV designer must be aware of the latest UAV developments; current technologies; know lessons learned from past failures; and they should appreciate the breadth of UAV design options.
