Special Issue Information
Dear Colleagues,
Nowadays, communication technologies are urgently required for channel capacity, confidentiality, and transmission rate. Orbital angular momentum (OAM) multiplexing technology represents a new method that could solve the channel capacity crisis and improve the performance of network bandwidth. Beyond optical wavelengths, OAM is becoming an important concept in electron, X-ray, and radio frequency beams. OAM applications have impacted various fields, ranging from optical manipulation, non-linear and quantum optics, to imaging. Nevertheless, the transmission performance of the OAM energy is limited due to certain interference factors. Therefore, new technologies for generating OAM power with the characteristics of high order, high purity, wide bandwidth, etc., are urgently needed. This Special Issue plans to give an overview of the most recent advances in the field of OAM designs, and their applications in diverse areas. This Special Issue will focus on providing selected contributions on advances in the purity, efficiency, and bandwidth of orbital angular momentum structures, as well as other related technologies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
