Orthogonality of the characteristic modes with respect to weight operator generalized eigenvalue equation (GEE), and in far-field, is investigated case lossy conducting dielectric objects. Linking radiated power shown provide orthogonal far fields lossless case. In case, both orthogonality modal currents are satisfied Hermitian inner products only for sufficiently symmetric geometries, such as ...

A unification of characteristic mode decomposition for all method-of-moment (MoM) formulations the field integral equations describing free-space scattering is derived. The work based on an algebraic link between impedance and transition matrices, latter which was used in early definitions modes uniquely defined scenarios. This also makes it possible to extend known application domain any other...

The bioethanol is playing an increasingly important role in renewable energy in China. Based on the theory of circular economy, integration of different resources by polygeneration is one of the solutions to improve energy efficiency and to reduce environmental impact. In this study, three modes of bioethanol production were selected to evaluate the life cycle energy efficiency and environmenta...

this study proposes a method employing thermogravimetric analysis (tg) to predict pollutionlevels by heavy metals (cr, cu, ni, zn, pb, cd and hg) in port sediments close to urban and industrial sitesfrom bay of cádiz. for this purpose, the thermogravimetric results of 14 sediment samples were recorded andshowed two characteristic ranges of temperatures (w1 as weight loss, %: 200-650°c) vs. (w2 ...

BACKGROUND Although enhanced temporal summation (TS) and conditioned pain modulation (CPM), as characteristic for central sensitization, has been proved to be impaired in different chronic pain populations, the exact nature is still unknown. OBJECTIVES We examined differences in TS and CPM in 2 chronic pain populations, patients with both chronic fatigue syndrome (CFS) and comorbid fibromyalg...

The paper presents the design of a hybrid controller used to control the movement of a ship in different operating modes, thereby improving the performance of basic maneuvers. This task requires integrating several operating modes, such as maneuvering the ship at low speeds, steering the ship at different speeds in the course or along the trajectory, and stopping the ship on the route. These mo...

Applying the recently developed formalism of quantum-state transformation at absorbing dielectric four-port devices [L. Knöll, S. Scheel, E. Schmidt, D.-G. Welsch, and A.V. Chizhov, Phys. Rev. A 59, 4716 (1999)], we calculate the quantum state of the outgoing modes of a two-mode squeezed vacuum transmitted through optical fibers of given extinction coefficients. Using the Peres–Horodecki separa...

A wide, multimode segment of a dielectric optical waveguide, enclosed by Bragg reflectors and evanescently coupled to adjacent port waveguides, can constitute the cavity in an integrated optical microresonator. It turns out that the device can be described adequately in terms of an approximate coupled mode theory model which involves only a few guided modes as basis fields. By reasoning along t...

The Advanced Range Telemetry (ARTM) program is a tri-service telemetry modernization project whose goal is to assure that all Department of Defense (DoD) test and training ranges are able to use telemetry as necessary to carry out their respective missions. Multi-h Continuous Phase Modulation (CPM) has been selected by the ARTM JPO as the Tier II ARTM waveform, because it offers significant imp...
