A D-Band Waveguide-SIW Transition for 6G Applications [PDF]
Journal of Electromagnetic Engineering and Science, 2022 In this work, a design of a transition from a standard D-band waveguide to substrate integrated waveguide (SIW) technology is presented for 6G applications. The waveguide is connected to an SIW by carving a slot at the bottom metal of the printed circuit

Transition metal d-band occupancy in skutterudites studied by electron energy-loss spectroscopy [PDF]
, 2007 The transition-metal 3d occupancy of a series of thermoelectric skutterudites is investigated using electron energy-loss spectroscopy. We find that bonding causes an emptying of the 3d states in the binary skutterudites CoP3, CoAs3, CoSb3, and NiP3 ...

Transmission of 4096-QAM OFDM at D-band
Optics Express, 2023 We experimentally demonstrate the transmission of multi-order quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) millimeter wave signals at D-band. Meanwhile, the system nonlinearity analysis is also given, which is originated from the unsatisfactory optoelectronic devices, multi-order QAM and the high peak-to ...

Colloidal CuFeS2 Nanocrystals: Intermediate Fe d-Band Leads to High Photothermal Conversion Efficiency [PDF]
, 2016 We describe the colloidal hot-injection synthesis of phase-pure nanocrystals (NCs) of a highly abundant mineral, chalcopyrite (CuFeS2). Absorption bands centered at around 480 and 950 nm, spanning almost the entire visible and near infrared regions ...

Indoor Radio Channel Modeling at D-Band Frequencies
2022 16th European Conference on Antennas and Propagation (EuCAP), 2022 This paper presents indoor radio channel measurements and models at D-band frequencies. A Line-of-Sight (LOS) alpha-beta-gamma path loss model is created based on indoor measurements up to 8.5 m in a laboratory and office room, resulting in a floating intercept alpha of 34.2 dB, PL exponent beta 1.9 and frequency dependency gamma 1.9.

Correlation between topological band character and chemical bonding in a $\mathbf{Bi_{14}Rh_{3}I_{9}}$-based family of insulators [PDF]
, 2015 Recently the presence of topologically protected edge-states in Bi$_{14}$Rh$_3$I$_9$ was confirmed by scanning tunnelling microscopy consolidating this compound as a weak 3D topological insulator (TI).

Distinct topological properties in Ce monopnictides having correlated f electrons: CeN vs. CeBi
Physical Review Research, 2020 The hitherto-studied topological nature in Ce monopnictides (CePn) has been discussed based solely on their p-d band inversion, despite the existence of f electrons.

DFT study on ORR catalyzed by bimetallic Pt-skin metals over substrates of Ir, Pd and Au
Nano Materials Science, 2023 Bimetallic Pt-skin catalyst is a class of near-surface alloy (NSA) that owns a high degree of control over composition. Herein, density functional theory (DFT) is used to calculate the energetics of oxygen reduction reaction (ORR) on Pt-skin over Ir, Pd ...

D-Band Perfect Anomalous Reflectors for 6G Applications
IEEE Access, 2021 We demonstrate anomalous reflectors at 140 GHz for the application of 6G communication coverage expansion. The reflectors are designed on cyclo-olefin polymer (COP) substrates on the basis of measured complex permittivity and conductivity at millimeter ...
