Momentum Sudut (AM) telah dianggap sebagai dimensi baharu penghantaran wayarles serta sifat intrinsik gelombang Elektro-Magnetik (EM). Setakat ini, AM digunakan sebagai mod diskret bukan sahaja dalam keadaan kuantum, tetapi juga dalam pembentukan rasuk statistik. Secara tradisinya, nilai berterusan AM diabaikan dan hanya nombor mod terkuantisasi dikenal pasti. Walau bagaimanapun, penemuan terbaru tentang elektron dalam gerakan lingkaran yang menghasilkan sinaran berpintal dengan AM, termasuk Momentum Sudut Putaran (SAM) dan Momentum Sudut Orbital (OAM), membuktikan bahawa nilai berterusan AM tersedia dalam rasuk gelombang EM statistik. Ini juga didedahkan oleh apa yang dipanggil OAM pecahan, yang dilaporkan dalam rasuk OAM optik. Kemudian, sebagai dimensi baharu dengan medan nombor nyata berterusan, AM sepatutnya menjadi spektrum tertentu, serupa dengan spektrum frekuensi biasanya dalam pemprosesan isyarat wayarles. Dalam surat ini, kami mentakrifkan spektrum AM secara matematik dan menunjukkan aplikasi dalam analisis teori maklumat, yang dijangka menjadi alat yang cekap untuk komunikasi wayarles masa hadapan dengan AM.

Abstract: Angular Momentum (AM) has been considered as a new dimension of wireless transmissions as well as the intrinsic property of Electro-Magnetic (EM) waves. So far, AM is utilized as a discrete mode not only in the quantum states, but also in the statistical beam forming. Traditionally, the continuous value of AM is ignored and only the quantized mode number is identified. However, the recent discovery on electrons in spiral motion producing twisted radiation with AM, including Spin Angular Momentum (SAM) and Orbital Angular Momentum (OAM), proves that the continuous value of AM is available in the statistical EM wave beam. This is also revealed by the so-called fractional OAM, which is reported in optical OAM beams. Then, as the new dimension with continuous real number field, AM should turn out to be a certain spectrum, similar to the frequency spectrum usually in the wireless signal processing. In this letter, we mathematically define the AM spectrum and show the applications in the information theory analysis, which is expected to be an efficient tool for the future wireless communications with AM.
