In this paper, we propose a metamaterial (MTM)-based low-profile wideband antenna and its array using substrate integrated cavity (SIC) feed structure for 5G wireless cellular networks. The proposed consists of two sets square mushroom-like arrays; semi-ground plane microstrip line-fed bow-tie radiator. Due to the unique in-phase reflection characteristic metamaterial, performance is maintained...

We integrate a bow-tie antenna on thin-film lithium niobate (TFLN) phase modulator to form an electromagnetic E-field sensor. The fiber-coupled TFLN chip is probed by two-tone optical local oscillator generated using external modulator, which after appropriate filtering allows the system act as photonic down-converter. compatible with use of balanced detection, enabling improved signal-to-noise...

Moderate Resolution Imaging Spectroradiometers (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) radiometers, flown onboard Terra/Aqua and Suomi National Polar-orbiting Partnership (S-NPP)/Joint Polar Satellite System (JPSS) satellites, are capable of providing superior sea surface temperature (SST) imagery. However, the swath data of these multi-detector sensors are subject to seve...

Despite being the sum of decentralized and uncoordinated efforts by heterogeneous groups and individuals, the World Wide Web exhibits a well defined structure, characterized by several interesting properties. This structure was clearly revealed by Broder et al. [4] who presented the evocative bow-tie picture of the Web. Although, the bow-tie structure is a relatively clear abstraction of the ma...

AIMS To create a clinically useful classification for post-keratoplasty corneas based on corneal topography. METHODS A total of 360 topographic maps obtained with the TMS-1, from 95 eyes that had undergone penetrating keratoplasty (PKP), were reviewed independently by two examiners in a masked fashion, and were categorised according to a proposed classification scheme. RESULTS A high intero...
