Feed model for the tapered slot antennas [PDF]
2008 4th International Conference on Ultrawideband and Ultrashort Impulse Signals, 2008 In this paper we will describe the feed model for the tapered slot antennas (TSAs) and will find one of the important parameter of this model - transformation coefficient.

Multi-Feed Metasurface Antennas: Direct Numerical Design and Experimental Validations
IEEE Access, 2023 This paper provides new designs and realizations of leaky-wave (LW) metasurface (MTS) antennas fed at multiple points. The design technique is based on the direct integral-equation solution by the Method of Moments (MoM).

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Random Beam-Based Non-Orthogonal Multiple Access for Low Latency K-User MISO Broadcast Channels
Sensors, 2021 In this paper, we propose random beam-based non-orthogonal multiple access (NOMA) for low latency multiple-input single-output (MISO) broadcast channels, where there is a target signal-to-interference-plus-noise power ratio (SINR) for each user.
