Monitoring nitrogen utilization efficiency and soil temperature in agricultural systems for
timely intervention is essential for crop health with reduced environmental pollution. Herein …

A specially designed metallic E-shaped fractal-based perfect metamaterial absorber (PMA)
with fairly wideband absorptivity in the K-and Ka-bands of the microwave regime was …

Broadband absorption in the terahertz regime is a challenge and onerous to realize with a
single layer metasurface. Self-similarity in fractal structures are exploiting metamaterial …

Broadband metasurface-based devices are essential and indispensable in modern wireless
communication systems. This paper presents an ultra− wideband and wide incident angle …

The inherent bandwidth limitations make it quite challenging to achieve the wideband
response of metamaterial absorbers. In this paper, a metamaterial absorber based on …

A polarization-insensitive multi-band metamaterial absorber comprised of four concentric
rectangular rib structures, mounted over a dielectric medium, was investigated. The …

Ultra-wideband metamaterial absorber comprising zirconium nitride (ZrN)-based
metasurface was investigated. In particular, the metasurface had three different kinds of …

In this paper, we propose a tunable graphene metamaterial absorber (TGMA) as a
bifunctional terahertz sensor. The TGMA can excite one peak with a maximum absorption of …

Multiband absorption is the interest of the microwave communities due to several
applications in sensing, filtering, and stealth. Usually, the stacking of metal and dielectric …

We report an efficient approach to enhance terahertz (THz)-guided modes for realizing
subwavelength thick metamaterial devices (MMD). Here, a combination of hollow and slitted …
