Dekker begins with metallic conduction. He provides a thorough treatment of the classical Drude-Lorentz model before introducing quantum corrections. A standout feature in these chapters is the explanation of thermal properties , such as the Wiedemann-Franz law, which relates thermal conductivity to electrical conductivity. This section is crucial for understanding why certain metals (like copper and silver) are industry standards, explaining resistance, superconductivity, and thermoelectric effects.

In the vast library of technical literature, certain texts endure not merely because of historical significance, but because of the clarity and rigour with which they present fundamental concepts. A.J. Dekker’s Electrical Engineering Materials is one such definitive text. While modern curriculums often prioritize the latest semiconductors and nanomaterials, Dekker’s work remains a vital bridge between pure physics and practical electrical engineering. The Author and Context A.J. Dekker was a prominent physicist and educator. His approach to writing textbooks—most notably his cover-all text Solid State Physics —was characterized by a mathematical rigour that was accessible to engineering students without sacrificing physical insight. Electrical Engineering Materials was written to address a specific gap: engineering students needed to understand the behavior of materials (conductors, insulators, and magnetics) but often lacked the deep quantum mechanical background required for pure physics texts. Core Philosophy: Physics for Engineers The central thesis of Dekker’s book is that the macroscopic properties of materials used in electrical engineering—such as conductivity, permeability, and dielectric strength—cannot be fully understood through empirical formulas alone. Instead, Dekker argues that these properties are manifestations of atomic and molecular behavior. Vegamovies Varane Avashyamund Access
Dekker navigates the complex world of magnetism by differentiating between diamagnetism, paramagnetism, and ferromagnetism. He explains the physics behind magnetic domains and hysteresis loops, which are fundamental to the design of transformers, inductors, and magnetic storage media. The text avoids getting lost in advanced quantum spin dynamics, focusing instead on the functional behavior of magnetic materials in circuits.
This is often considered the strongest section of the book for practicing engineers. Dekker treats dielectrics with the same rigour as conductors. He elucidates the difference between electronic, ionic, and orientational polarization . For engineers designing capacitors or high-voltage cables, his breakdown of dielectric loss and breakdown mechanisms is invaluable. He connects the microscopic dipole moment to the macroscopic permittivity, a concept often glossed over in less rigorous texts.
Unlike handbooks that simply list material properties, Dekker derives them. He moves systematically from the to band theory , providing the reader with the intellectual tools to predict how a material will behave under varying temperatures, fields, and frequencies. Structural Breakdown of the Text The book is typically structured to guide the student from the simplest concepts to complex applications:
