Special Issue Information
Dear Colleagues,
This Special Issue will focus upon experimental techniques and theoretical modeling for generating coherent millimeter and THz waves useful for sensing applications. One of the primary topics will be the generation of coherent THz waves from antennas formed from the intrinsic Josephson junctions in the high-temperature superconductor Bi2Sr2CaCu2O8+δ (Bi2212) and in related cuprates. This can be managed by designing various shapes of thin Bi2212 crystals. The earliest most common shapes were rectangular, but other shapes such as slitted annuli were made, and regular arrays of such shapes were found to emit with increasing output power, but still below the desired minimum power of 1 mW. This Special Issue will focus upon the design of antennas and antenna arrays that have the potential to generate coherent millimeter and/or THz waves with output powers that can approach or exceed 1 mW. Shapes such as circular disks, equilateral triangles, ellipses, squares, pentagons, hexagons, and heptagons, and especially slitted variations of those shapes with degenerate modes that can increase the output power will be the focus of this Special Issue.

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. Sensors 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 2600 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.
