Transmission of 4096-QAM OFDM at D-band
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 ...

Resurgence of superconductivity and the role of dxy hole band in FeSe1−x Te x
Iron-chalcogenide superconductors display rich phenomena caused by orbital-dependent band shifts and electronic correlations. Additionally, they are potential candidates for topological superconductivity due to the band inversion between the Fe d bands ...

Strain and ligand effects in Pt-Ni alloys studied by valence-to-core X-ray emission spectroscopy
Experimental detection of the Pt 5d densities of states in the valence band is conducted on a series of Pt-Ni alloys by high energy resolution valence-to-core X-ray emission spectroscopy (VTC-XES) at the Pt L3-edge.

A D-Band Hybrid-Type CMOS Phase Shifter with Full 360° Phase Coverage [PDF]
This paper presents a D-band phase shifter fabricated using 65-nm CMOS technology that provides continuous full 360° phase shift. To achieve moderate insertion loss with low DC power, a hybrid-type topology is adopted by combining a 180° reflection-type ...

A Circularly Polarized Antenna in D-Band [PDF]
In this paper a 140 GHz circularly polarized antenna is studied. The motivation of this work is to propose a suitable antenna configuration to reduce the subsequent manufacturing cost and complexity. The resultant antenna consists of a circular waveguide feed and a dielectric cover which is used to increase antenna directivity.

Ligand field tuning of d-orbital energies in metal-organic framework clusters
Linker functionalization is a common route used to affect the electronic and catalytic properties of metal-organic frameworks. By either pre- or post-synthetically installing linkages with differing linker moieties the band gap, workfunction, and exciton

Tuned d-band states over lanthanum doped nickel oxide for efficient oxygen evolution reaction
The d-band state of materials is an important descriptor for activity of oxygen evolution reaction (OER). For NiO materials, there is rarely concern about tuning their d-band states to tailor the OER behaviors.

Disruptive TRX design for the D-band
This paper presents an architecture for broadband wireless transceivers operating in the D-band with the aim of covering tens of GHz of band over the air with a limited bandwidth per channel at the baseband. The main idea is to combine several baseband channels in a multi-channel radio-frequency (RF) signal.
