Wireless communication systems, including smartphones, Wi-Fi, GPS, and NFC, are vital to modern life. As data demands grow, higher bandwidths are needed, pushing technologies toward higher frequencies such as millimeter-wave and terahertz spectra, used in 5G/6G and the Internet of Things. These applications require devices with low energy consumption, minimal signal attenuation, and high miniaturization, crucial for integration into portable electronics.Ferroelectric materials offer great potential due to their low dielectric losses at microwave frequencies. However, conventional perovskite...
