A novel 0.5THz integrated antipodal curvilinearly tapered slot antenna (ACTSA) with circular polarization is introduced in this paper. The proposed antenna is fed by traditional waveguide and circular ...

This paper proposes a circularly polarized horn antenna with tapered elliptical waveguide and it employs a tapered elliptical waveguide polarizer to achieve wideband circular polarization. The ...

The constructive interference of surface plasmon polaritons (SPP) launched by nanometric holes allows us to focus SPP into a spot of high near-field intensity having subwavelength width. Near-field ...
