To realize the functions of infrared transparent as well as radar double- pass Band
A Y loop and Y slot compound element Frequency Selective Surface (FSS) structure is proposed
which takes an infrared transparent inductive mesh as a substrate. The proposed structure is analyzed based on Galerkin spectral method. The transitivity of infrared (3um-5um) as well as the radar double passed band with two resonance frequencies (31GHz and 54GHz) is discussed. The result reveals that this structure has function of infrared transparent as well as stable radar double-band filter with effective shielding effect on S-band and C-band radar electromagnetic waves. The design with multiple passband is suitable for radar/IR composite guidance and it also offers a kind of new thinking way of design for multi-mode compound guidance systems. 2011 Trans Tech Publications.

We investigated electro-optic modulator structures to target low drive voltage
high-speed modulation
and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study
the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films
the frequency-voltage-size performances for 2.5GHz
10GHz
40GHz
and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V
1.6V
3.0V and 4.8V
respectively
for the ideal film with r51=730 pm/V at 1550nm wavelength
where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm
0.8 mm
0.4 mm and 0.2 mm
respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation
an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured
which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.
