In this paper, we present a metal-only transmission metasurface adopting dual-layer elements with I-shaped grooves etched on each layer, which is designed for orbital angular momentum (OAM) generation. The special arrangement of the results in wider phase compensation range, and by varying length grooves, full 360° coverage amplitude more than −2 dB can be achieved at 10 GHz. As proof concept, composed 400 designed, fabricated, measured. simulated measured suggest that OAM transmitted waves...
In this communication, a dual-band, orthogonal polarization transmission metasurface antenna operating at 6.5 GHz and 9.5 is proposed. The element of transmitarray composed only two identical layers metal plates, with air medium filling the space between upper lower layers. Each layer has four sets staggered I-slots, thus ensuring dual-frequency operation. Moreover proposed overcomes challenge achieving full 360-degree phase shift in dual-layer metal-only structures without any additional...
The clinical use of flattening filter free (FFF) radiotherapy has significantly increased in recent years due to its effective enhancement dose rates and reduction scatter dose. A proposal been made adjust the incident electron angle accelerator expand application FFF beams areas such as large planning target volumes (PTVs). However, inherent softening characteristics non-uniformity lateral distribution inevitably lead dosimetry errors, especially for ionization chambers widely used...
