Metajet berukuran mikro dapat mengarahkan layar cahaya untuk perjalanan antarbintang

Para peneliti telah mengembangkan perangkat berukuran sangat kecil yang menggunakan cahaya untuk mengendalikan pergerakan ke berbagai arah, yang memajukan potensi pesawat ruang angkasa bertenaga cahaya. Metajet yang terbuat dari silikon ini telah diuji di laboratorium dan menunjukkan hasil yang menjanjikan untuk mengarahkan layar besar melalui ruang angkasa. Terobosan ini dapat membantu mengatasi batasan saat ini dalam mengarahkan kapal semacam itu melintasi jarak yang sangat jauh.

Para ilmuwan di Texas A&M University menciptakan metajet, sebuah wafer silikon kecil berukuran sekitar 0,01 milimeter. Perangkat ini memiliki permukaan meta dengan pilar-pilar mikroskopis yang membiaskan cahaya untuk menghasilkan momentum yang terkendali. Hal ini memungkinkan perangkat untuk bergerak secara vertikal maupun horizontal, tidak seperti layar cahaya tradisional yang sebagian besar hanya mengandalkan pantulan.
