文摘

We in this paper introduce three layers of metamaterial waveguide for an application as cavity resonator where structure deals with IR region of the electromagnetic spectrum, which ranges from 1200 nm to 1775 nm. Finite difference time domain method shows that waveguide predicts unusual behaviour with respect to above spectrum. Simulation result confirms that feeble power is realized at lower and higher wavelength however same device deals with massive power at middle range regime. For example; power attains the order of 10443 at wavelength, 1550 nm. Finally, this paper suggests that above three layers of metamaterial waveguide may be a good candidate for cavity resonator.
