In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

Electro-optic switching of reflection and refraction is experimentally demonstrated in metasurface liquid crystal cell. Negative metasurface is fabricated by focused-ion-beam milling, and twisted nematic cells are constructed with complementary double-split ring resonator and V-shape slot antenna metasurface. By application of an external voltage, electro-optic switchings are achieved in reflec...

This paper aims to produce a high data capacity and miniaturized flexible chipless RFID tag based on the frequency signature using Modified Complementary Split Ring Resonator (MCSRR). The proposed 19 bits shifting technique consists of five slotted overlaying MCSRR with Different Width (MCSRR DW) structures dimension 48 mm × mm. structure is designed by (Polyethylene Terephthalate) PET substrat...

We present a compact ultra-wideband (UWB) antenna integrated with sharp notches with a detailed analysis of the mutual coupling of the multiple notch resonators. By utilizing complementary split ring resonators (CSRR) on the radiating semi-circular patch, we achieve the sharp notch-filtering of various bands within the UWB band without increasing the antenna size. The notched frequency bands in...

We propose a short period undulator based on the electromagnetic field pattern in THz-driven split ring resonator structure. An analytical model is developed that allows us to assess key performance parameters of and estimate emitted radiation spectrum. Different geometric configurations are compared detail using numerical simulations. A 100 MeV electron bunch with 5 pC charge shown emit narrow...
