A new quality factor (Q abs) characterising power absorption by electrically small structures ranging from antennas to lossy objects is defined. In analogy to the radiation quality factor (Q rad), which is evaluated using the antenna radiated fields

This paper presents a thin absorbing structure comprising an array of finitely conductive terminal-loaded dipoles spaced about half a wavelength apart and located above a ground plane. We show that if the antennas are terminated with proper load impe

Magnetic communication systems are most often analyzed assuming magnetoquasistatic (MQS) conditions, which neglect full-field terms and high-frequency (HF) effects in the transmitting and receiving coils. Such approximations may lead to nonoptimal de

Methods employing auxiliary sources are applied to electromagnetic scattering problems by 2-D noncircular scatterers. Specific cases are considered for which the singularities of the analytic continuation of the scattered field into the interior of t

Motivated by the lack of scalability of the source-model technique (SMT) to many-scatterer problems, a new SMT-based method for 3-D many-scatterer problems is developed. The large time complexity of the SMT is reduced by deriving an implicit compact
