This is a textbook for undergraduate courses on radio astronomy. Written by an active professor and researcher in the field, it begins by explaining why conducting observations at radio frequencies is so important, then reviews essential physics concepts corresponding to a sophomore-level curriculum or higher. Next, the book introduces students to single dish telescopes and interferometers. The most commonly encountered emission mechanisms seen in radio astronomy are then explained, along with examples of astronomical sources broadly divided into the types of sources seen in galactic and extragalactic observations. Each chapter provides examples and exercises suitable for homework assignments. Also included is an appendix of useful supplementary material. Altogether, the book is a comprehensive, yet digestible starting point for physics and astronomy undergraduates looking to understand the basics of radio astronomy.

This book aims at making readers develop a better understanding of electrostatic fields using the form of problems and puzzles (summarized as “questions” hereafter) and answers, instead of tedious explanations in ordinary textbooks. The book is filled with the questions with unexpected answers and questions often misunderstood or rarely completely understood, most of which are original. The questions in the book look simple and very easy to answer at a glance; nevertheless, once students try to solve them, they will find that the questions are really tough nuts to crack. Teachers can also use the questions in the book in their classes. Not only from an academic or an educational point of view, the book is useful also to engineers working in such fields as electrical discharges and their applications, high voltage equipment in DC and AC circuits as well as electrostatic devices. This is because the book introduces various practical applications related to electrostatic fields. The original ideas of the book are based on the following Japanese book written by one of author; T. Takuma: Panorama of Electric Fields (in Japanese) IEE, Japan, 2003. This English version of the book been thoroughly revised and improved with several new questions added.

This book presents the theory, analysis, and design of multiband dual-function microwave and millimeter-wave CMOS radio frequency integrated circuit (RFIC) filter-switches capable of simultaneous switching and filtering, which are relevant for advanced multiband RF systems. Typical microwave and millimeter-wave switches are designed only for switching purposes without considering frequency selectivity or filtering. A separate filter is normally needed to be used with a switch to provide a filtering function. This conventional design approach hence leads to higher insertion loss, larger size and higher cost for RF systems. RF systems operating over multiple bands provide numerous advantages and offer more capabilities for communications and sensing than their single-band counterparts. A concurrent multiband system enables one single system to be used over multiple bands simultaneously, leading to optimum size, cost, and power consumption, together with ease of system implementation. Truly concurrent multiband systems require many components to work on multiple bands simultaneously, including concurrent multiband switches. Microwave and millimeter-wave integrated circuits using silicon-based CMOS (or related BiCMOS) RFICs are less expensive and better suited to direct integration with digital ICs than those using III-V compound semiconductor devices. CMOS RFICs are also small and offer low power consumption, making them suitable for portable battery-operated systems. Accordingly, CMOS RFICs are very attractive for RF systems and are the principal choice for commercial wireless markets. The content is divided into six chapters, the first four of which describe and address band-pass, high-pass, and low-pass filters, as well as multiband band-pass filters, the fundamentals of switches, and various switch architectures including single-pole single-throw (SPST), single-pole double-throw (SPDT), transmit/receive (T/R), and ultra-high-isolation switches, the fundamentals and models of MOSFETs used in the design of switches, and the essentials of CMOS RFIC design needed for the filter-switches presented in this book. In turn, the fifth chapter presents the core of the book, namely the design, simulation, and measurement of various CMOS dual-band dual-function SPDT and T/R switches capable of concurrent switching and filtering, as examples to illustrate the design of multiband dual-function filter-switches. These components operate in two different frequency bands centered at approximately 40 and 60 GHz and 24 and 60 GHz. Lastly, a summary and conclusion are provided in Chapter 6.
