## Abstract This article introduces the design of a small (30 mm Γ 35 mm Γ 1.6 mm) bandβrejected Uβslotted planar antenna on FR4 substrate having a relative permittivity of Ξ΅~r~ = 4.4 for Impulse Radio Ultra Wide Band (IRβUWB) systems. The antenna is fed by a microstrip line and rejects the frequen
The influence of a.c. electric field (5kHz) on the IR and FIR spectra of the nematic phase of some liquid crystals with strong positive dielectric anisotropy ( Eaz 10 -20) and weak negative dielectric anisotropy (6,~ -0,2 -0,7) was investigated. The changes in the half-widths and integral intensity
