"This single volume provides a comprehensive introduction and explanation of both the theory and practice of 'Planar Near-Field Antenna Measurements', from its basic postulates and assumptions, to the intricacies of its deployment in complex and demanding measurement scenarios. To do this the book initially examines the properties of antennas that allow them to enhance the free space interaction of electronic systems and this leads into a full description of the theory of 'Planar Near-Field Scanning'."

"The authors of this work (doctors, engineers and researchers) have endeavored to supply validated and easily understandable scientific information on the electromagnetic fields and their biological and health effects. After a general review of the physics of the waves and a presentation of non-ionizing radiations, the authors review the main emission sources encountered in our daily environment. They summarize simply but as accurately as possible the current knowledge on their biological effects.The safety limits recommended by international organizations are presented for the different frequency ranges. ;"

"Buku yang berjudul "Geothermal reservoir engineering" ini ditulis oleh Malcolm A. Grant, Ian G. Donaldson, dan Paul F. Bixley. Buku ini membahas tentang geothermal, sistem, konsep dari geothermal tersebut."

"Muatan listrik pada kawat fasa yang bertegangan merupakan sumber medan elektrostatis dari saluran transmisi, sehingga kopling kapasitip antara kawat fasa dan kawat tanah menyebabkan induksi muatan listrik pada kawat tanah. Jika kawat tanah itu diisolasi terhadap tanah, maka beda potensial antara kawat tanah dan tanah dapat dimanfaatkan sebagai sumber daya. Daya ini terutama digunakan untuk mencatu beban-beban kecil yang terdapat dekat saluran tersebut. Besar daya yang dapat disadap melalui kawat tanah tergantung pada tegangan transmisi, konfigurasi saluran, serta panjang kawat tanah yang diisolasi. Beberapa faktor seperti faktor transposisi juga berpengaruh terhadap besar daya tersebut.

Electric fields on the conductor line are source of electrostatic fields of overhead transmission line, so that a coupling capacitive between conductor and ground wire can make induction on ground wire. If ground wire is isolated from earth, the voltage across earth and ground wire can be use as source of power. The amounts of power depend on voltage, configuration, and lengths of transmission line. Some factor such as transposition factor also to have influence on amount of power."
