This deposit contains the preprint and numerical simulation source code for the PMER-T (Passive Metasurface Electromagnetic-Resonance Tokamak) reactor concept. The core innovation of this work is the transition from active, energy-intensive external heating systems to a passive microwave energy recovery system. By integrating CVD-diamond windows with microstrip metasurfaces into the vacuum vessel wall, the system captures chaotic electron cyclotron radiation (35 GHz) and re-emits it as resonant ion-cyclotron heating (19 MHz). This process effectively bridges the "Spitzer thermal detachment" gap, heating deuterium ions to thermonuclear temperatures (13.06 keV) using the plasma's own radiative losses. Key Features: Steady-State Operation: Demonstrates a non-inductive current drive (ECCD) of 136.7 MA, eliminating the need for a pulsed central solenoid. High Efficiency: Numerical 1D transport modeling shows an engineered Q-factor of \(\approx 16.3\). Moderate Magnetic Field: Optimized for 1.25 T to match commercial Ka-band radio-frequency components. Safety: Integrated MHD-stability control through adaptive phase-shifting rectennas.
