Can Creek Audio stand out in 2026 as it enters the crowded speaker market and rethinks its amplifier strategy? After nearly 45 years of doing things the hard way and usually the right way, Creek Audio ...

Abstract: Helically corrugated waveguides are critical components in many high-power microwave systems. However, theoretical analysis of their dispersion characteristics within the overmoded ...

Table-top sources that generate both extreme ultraviolet light and soft X-rays through high-harmonic generation of ultrafast infrared laser pulses look set to perform tasks previously accessible using ...

Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on which a beam of light can operate is equal to half its ...

Abstract: In this paper, we investigate the eigenmode of a parallel-plate waveguide formed by two impenetrable metasurfaces with arbitrary homogeneous surface capacitances. We begin by deriving the ...
