Penelitian studi tentang Metamaterials (MTMs) dalam beberapa tahun terakhir telah meningkat sangat pesat. Metamaterials yang di sebut juga artificial material atau  Left Handed (LH) material adalah material yang tidak ada dialam dimana strukturnya direkayasa oleh manusia yang memiliki dua atau lebih properties yang khusus, misalkan pada Double Negative (DNG) material yang memiliki μ negative dan  ε negative. Beberapa pendekatan dalam mendesign metamaterial yaitu pendekatan resonant dan pendekatan Transmission line. Model transmision line yang pertama adalah Right Handed Transmission lines (RH TL) yang dimodelkan dalam sebuah unit sel sebagai rangkaian dan shunt kapasitor shunt(CR), yang kedua adalah Left Handed Transmission Line (LH TL) dimodelkan dalam sebuah unit sel sebagai rangkaian kapasitor seri(CL) dan induktansi shunt(LL). gabungan dari dua buah model transmission line ini disebut Composite Right-left Handed Transmission Line(CRLH TL)  dan ini menjadi dasar dalam mendesign metamaterial. CRLH transmission line dimodelkan dalam sebuah unit sel sebagai rangkaian kapasitor seri(CL), induktansi seri(LR) dan induktansi shunt (LL) serta induktansi shunt(LL). CRLH TL memiliki negatif, nol dankonstanta propagasi positif sesuai dengan karakteristik dari permitivitas efektif dan permeabilitas[1]. Hasil pengukuran bandpass filter menggunakan saluran transmisi CRLH satu sel menunjukkan frekuensi cutoff pada -10dB terletak pada frekuensi 3.016 GHz pada highpass filter dan 5.359GHz pada lowpass filternya. Sedangkan frekuensi 3.4 GHz terletak pada -4.8415 dB sedangkan frekuensi 4.8 Ghz terletak pada -4.753 dB. Hasil dari perancangan menunjukkan bahwa saluran transmisi CRLH satu sel dapat memenuhi spesifikasi yang diminta.

A method is proposed to obtain heave motion information based on the Longuet-Higgins wave model. The Longuet-Higgins wave model which is closer to the sea wave is introduced. Based on it, random process of the noise is analyzed and the highpass filter is designed to reduce errors. Then it is the key point in this article that an adaptive algorithm is put forward because of the complexity of the waves. The algorithm adjusts the cutoff frequency to reduce the amplitude attenuation of the filter by analyzing the wave. For the same reason the comprehensive parameter of the phase compensation can be also obtained by the algorithm. Simulation measurement results show that under the rough sea situation the maximum value of absolute error is 0.4942 m according to the normal method, the method is 0.1170 m, and the average error ratio of the rough sea test reduces to 3.89% from 12.54%, which demonstrates that the adaptive filter is more effective in measuring heave movement. A variety of simulation cases show that the adaptive filter can also improve the precision of the heave motion under different sea situations.
