Antennas for Small Mobile Terminals

By: Kyohei Fujimoto,Koichi Itoh

With the progress and rapid increase in mobile terminals, the design of antennas for these small systems is becoming more and more important. This forward-looking volume offers professionals current and comprehensive coverage of the design, development, and implementation of small, compact, and lightweight antennas in mobile communication terminals. The book discusses a wide range of communication systems, from Radio-frequency identification (RFID), and near field communications (NFC), to wireless power transmission (WPT) and broadband wireless networks. Engineers learn how to use small antennas in mobile phones, wearable systems, laptop computers, radio watches, and broadband wireless networks such as WLAN and WiMAX. This definite reference covers the critical applications today’s professionals need to understand, from antennas for IoT and antenna design for 5G mm-wave devices, to body-centric communication systems and antennas for unmanned aerial vehicles.

Amorphous Chalcogenide Semiconductors and Related Materials

By: Keiji Tanaka,Koichi Shimakawa

This book provides introductory, comprehensive, and concise descriptions of amorphous chalcogenide semiconductors and related materials. It includes comparative portraits of the chalcogenide and related materials including amorphous hydrogenated Si, oxide and halide glasses, and organic polymers. It also describes effects of non-equilibrium disorder, in comparison with those in crystalline semiconductors.

Excitonic Processes in Solids

By: Masayasu Ueta,Hiroshi Kanzaki,Koichi Kobayashi,Yutaka Toyozawa,Eiichi Hanamura

An exciton is an electronic excitation wave consisting of an electron-hole pair which propagates in a nonmetallic solid. Since the pioneering research of Fren kel, Wannier and the Pohl group in the 1930s, a large number of experimental and theoretical studies have been made. Due to these investigations the exciton is now a well-established concept and the electronic structure has been clarified in great detail. The next subjects for investigation are, naturally, dynamical processes of excitons such as excitation, relaxation, annihilation and molecule formation and, in fact, many interesting phenomena have been disclosed by recent works. These excitonic processes have been recognized to be quite important in solid-state physics because they involve a number of basic interactions between excitons and other elementary excitations. It is the aim of this quasi monograph to describe these excitonic processes from both theoretical and experimental points of view. we take a few To discuss and illustrate the excitonic processes in solids, important and well-investigated insulating crystals as playgrounds for excitons on which they play in a manner characteristic of each material. The selection of the materials is made in such a way that they possess some unique properties of excitonic processes and are adequate to cover important interactions in which excitons are involved. In each material, excitonic processes are described in detail from the experimental side in order to show the whole story of excitons in a particular material.

Sketching Men

How to Draw Lifelike Male Figures, A Complete Course for Beginners (Over 600 Illustrations)

By: Koichi Hagawa

In Sketching Men, veteran art instructor Koichi Hagawa, PhD explains how to quickly capture the dynamic male form through two distinct styles of sketching: Very rapid (1-3 minute) line drawings that capture the essence of the subject's posture and movement--perfect for recording athletic action poses in the moment More finished tonal drawings, which take a bit longer to render (7-10 minutes), but fill in lots of interesting texture and wonderfully realistic details and nuances, including the play of light and shadow, three-dimensional form and a sense of mass and balance Learn to sketch the following: Individual body parts and their bones and muscles Objects held in the hands and with both arms Standing and sitting poses Transitions from prone and sitting poses to a standing pose Bending, reaching and leaning poses Pushing, throwing and dancing poses Folds, gathers and drape of clothing This book contains hundreds of detailed studies and helpful examples. Your sketches will improve rapidly as you learn all about how human anatomy--the skeleton, muscles and posture--all come together to express the uniquely male form. When you hone your line and tonal drawing skills with this book, all of your artwork will improve as a result, no matter the application: storyboarding, cartooning and graphic novels, illustration, formal drawings, painting and more!

Amorphous Semiconductors

By: Sándor Kugler,Koichi Shimakawa

Understanding the structural unit of crystalline solids is vital in determining their optical and electronic properties. However, the disordered nature of amorphous semiconductors, where no long-range order is retained, makes it difficult to determine their structure using traditional methods. This book shows how computer modelling can be used to overcome the difficulties that arise in the atomic scale identification of amorphous semiconductors. The book explains how to generate a random structure using computer modelling, providing readers with the techniques to construct realistic material structures. It shows how the optical and electronic properties are related to random structures. Readers will be able to understand the characteristic features of disordered semiconductors. The structural and electronic modifications by photon irradiation are also discussed in detail. This book is ideal for both physicists and engineers working in solid state physics, semiconductor engineering and electrical engineering.
