Microwave diplexers are often designed iteratively via manual channel-by-channel or resonator-by-resonator local optimization procedures due to high dimensionality in design variables and the complexity of structures. A one-off automated diplexer method is yet be developed. To achieve this, other than improved optimizers, an effective objective function (OF) critical allow optimizers find desir...

This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...

We construct quasi-one-dimensional topological and nontopological three-band lattices with a tunable band gap winding number of the flat band. Using full multiband mean field (MF) exact density matrix renormalization group (DMRG) calculations, we show explicitly how affects pairing superconductivity (SC) in Hubbard model attractive interactions. obtain excellent agreement between MF DMRG calcul...

The state-of-the-art speech enhancement has limited performance in estimation accuracy. Recently, deep learning, the Transformer shows potential to exploit long-range dependency by self-attention. Therefore, it is introduced improve accuracy from a noise mixture. However, address computational cost issue with self-attention, axial attention option i.e., split 2D into two 1D attentions. Inspired...

The 3psigma(u)D (3)Sigma(u) (+) Rydberg state of N(2) is studied experimentally using two high-resolution spectroscopic techniques. First, the forbidden D (3)Sigma(u) (+)-X (1)Sigma(g) (+) transition is observed for the first time via the (0,0) band of (14)N(2) and the (1,0) band of (15)N(2), using 1 extreme-ultraviolet +1 ultraviolet two-photon-ionization laser spectroscopy. Second, the Rydber...
