Their results show that gold helix photonic metamaterials can be used as broadband circular polarisers.
After removing the polymer template by plasma etching, they demonstrated gold-helix structures, shown in Fig. 4b, that work as a compact broadband circular polarizer [51].
This paper presents a design of a low-profile cavity-backed circular patch antenna for broadband applications.
In this paper, we present a single mode circular photonic crystal fiber (C-PCF) for broadband dispersion compensation covering 1400 to 1610 nm wavelength band over the telecommunication windows.
The mean-value method of predicting the dynamic response of a structure is applied to reduction of broadband noise radiated from thin, circular cylindrical shells during current tank manufacturing operations.
Helical plasmonic structures have attracted considerable attention owing to their extraordinary optical properties, such as negative refraction [1], and strong circular dichroism; they can potentially be used in broadband circular polarizers [2] and biosensing [3].
The objective is to design broadband synchronization regions for efficient piezoelectric energy harvesting from VIVs of circular cylinders.
The circular polarization-dependent absorption and radiation cause the arrays to exhibit extraordinary optical properties, including broadband circular polarization [2] and light absorption [3].
Square optical black hole (SOBH) has been proven to be a special and remarkably useful optical structure with broadband omnidirectional light absorption, and a device that is easier to fabricate than circular optical black hole (COBH).
The accuracy of the present method is assessed for broadband noise (with a broadened tone) from a flow with ReD= 4.6×104 and M= 0.21, past a circular cylinder of 30 cylinder-diameter span.
