In this paper, we theoretically study optical responses of tightly-coupled terahertz metamaterial. Unlike loosely-coupled one, tightly-coupled metamaterials exhibit resonant optical responses that are highly dependent on the interaction between each unit resonators. In order to predict optical response and spectral behavior of effective parameters of the metamaterials, a model based on coupled-mode theory is applied. Resonant optical response is shown to be highly dependent on the gap-size between the resonators which relates to the inter-unit coupling, and we show that this dependency implies the possibility of miniaturized metamaterials .
