MAT A hf - Jens Carstensen - Bog - Systime - Plusbog.dk

MAT A hf - Jens Carstensen - Bog - Systime - Plusbog.dk

MAT A hf udgør sammen med MAT C hf og MAT B hf grundbøgerne til matematik på A-niveau på hf. Honorerer kravene i læreplanen 2017 med bl.a. de nye emner funktioner af to variable og vektorfunktioner. I slutningen af kapitlerne er der fordybelsesafsnit, hvor eleverne selvstændigt kan udforske matematiske emner. Fordybelsesafsnittene kan bruges til at træne den nye del af skriftlig eksamen, hvor der indgår forberedelsesmateriale – eller man kan bruge dem som grundlag for projektarbejde. MAT A hf understøttes af opgavesamlingen MAT A hf opgaver.

Spoof Surface Plasmon Polaritons Antenna - Junping Geng - Bog - Springer Verlag, Singapore - Plusbog.dk

Spoof Surface Plasmon Polaritons Antenna - Junping Geng - Bog - Springer Verlag, Singapore - Plusbog.dk

This book investigates in detail some new spoof surface plasmon polaritons (SSPPs) structures and their applications to antenna. It introduces the working principle and radiation characteristics of directional antenna, omnidirectional antenna, reconfigurable antenna and phase-mode antenna based on SSPPs structure. Especially, the irregular SSPPs structure, such as T-shaped and m-shaped SSPPs structures, is introduced to low-profile end-fire antenna with vertical polarization; the rotated SSPPs structure is applied to CP end-fire antenna and omnidirectional antenna; PIN circuit combining with SSPPs structure is used to pattern reconfigurable antenna; the novel phase-mode SSPPs antennas with multi-modes are performed too. This book proposes a continuous method to develop the potentialities of the SSPPs antenna. And the readers can study the method or ideas of the SSPPs antenna, even graft the methods to other SSPPs antenna. The book is intended for undergraduate and graduate students who are interested in SSPPs antenna technology, researchers investigating high-performance antenna, and antenna design engineers working on multi-function antenna applications.

Electromagnetic Reciprocity in Antenna Theory - Martin Stumpf - Bog - John Wiley & Sons Inc - Plusbog.dk

Electromagnetic Reciprocity in Antenna Theory - Martin Stumpf - Bog - John Wiley & Sons Inc - Plusbog.dk

Provides a self-contained account on applications of electromagnetic reciprocity theorems to multiport antenna systems The reciprocity theorem is among the most intriguing concepts in wave field theory and has become an integral part of almost all standard textbooks on electromagnetic (EM) theory. This book makes use of the theorem to quantitatively describe EM interactions concerning general multiport antenna systems. It covers a general reciprocity-based description of antenna systems, their EM scattering properties, and further related aspects. Beginning with an introduction to the subject, Electromagnetic Reciprocity in Antenna Theory provides readers first with the basic prerequisites before offering coverage of the equivalent multiport circuit antenna representations, EM coupling between multiport antenna systems and their EM interactions with scatterers, accompanied with the corresponding EM compensation theorems. In addition, the text: Presents basic prerequisites including the definition of the notation, integral transformations, and EM reciprocity theorems in their general formExplores multiport antenna forward-scattering theorem, multiport antenna matching theorem and uniqueness theoremSupplements each chapter with a solved illustrative example Electromagnetic Reciprocity in Antenna Theory is an excellent text for EMC and antenna researchers and students of the subject as well.
